The present invention relates to a fireproof material for processing cigarette side smoke. This fireproof material that replaces conventional cigarette paper, or used in combination with a cigarette containing conventional cigarette paper, allows you to get Smoking product with reduced adverse selection smoke.

When Smoking tobacco products, particularly cigarettes, is formed of three types of smoke, namely mainstream smoke, exhaled smoke and side smoke. To remove the side of the smoke and exhaled smoke from enclosed spaces in which people can smoke, widely used filter materials. It is generally accepted that most of the smoke produced when Smoking, refers to the side smoke. Thus, there is a significant need to reduce the number of adverse smoke, which can be achieved by one or more of the following ways:

(i) a change in the composition of tobacco and characteristics of the density of the packing of the tobacco rod of the cigarette or cigar;

ii) change the paper wrapper of a cigarette or cigar;

iii) changing the diameter of the cigarette and composition of the contained tobacco and/or installation on the cigarette or cigar device for receiving the side of the smoke and/or to deal with its selection.

When trying to reduce the allocation side of the smoke offered various options that achnyh rods and cigarette paper. These designs in one way or another influenced the speed of free burning cigarettes or cigars, which led to the extinguishing lighted cigarettes or cigars, if it was not delayed for a long time. Such variants include special tobacco blend, cigarettes reduced diameter seals and multiple layers of cigarette tobacco in cigarette portions. Such designs can significantly slow down the speed of free burning cigarettes and thereby increase the number of inhalations is not unit length of the cigarette. In combination with the selected tobacco and/or design of the Smoking product, or regardless of the composition of tobacco, at the speed of free burning cigarette can be influenced by the composition of the cigarette paper. In this paper introduce chemicals that slow down the speed of free burning, chemicals, reducing side smoke, or use multiple wrappers of different types of cigarette paper with the same or different characteristics, and reduction of permeability to air. See, for example, canadian patent 1239783 and 1259008, and U.S. patent 4108151; 4225636; 4231377; 4420002; 4433697; 4450847; 4461311; 4561454; 4624268; 4805644; 4878507; 4915118; 5220930 and 5271419, as well as a patent application in the UK 2094130. Also tested cigarettes of reduced diameter, for example, described in U.S. patent 4637410.

It was suggested various devices to provide the I-cigarettes, mainly to prevent accidental ignition. They can contain (or not) different types of filters for filtering and thereby reduce the number of side smoke. Examples of such devices are shown in U.S. patents 1211071; 3827444; 3886954 and 4685477.

In addition, produced different types of mouthpieces that are designed primarily to minimize staining of the fingers of the smoker. Such devices can be connected to the end of a cigarette or installed on a cigarette, as shown in U.S. patent 1862679. Other cigarette enclosed in perforated one way or another wrapper for security and/or to fight side by smoke, as described in the patent Canada 835684 and in U.S. patent 3220418 and 5271419.

Devices that can be installed on a cigarette and can move along the cigarettes to control the rate of burning and hence the speed of free burning cigarettes, described in the patent UK 928089, in U.S. patent 4638819 and in the publication WO 96/22031. In the United Kingdom patent 928089 described a management tool, burning cigarettes, restricting the flow of air to the burning zone of the cigarette. It is assumed that due to the slow combustion of the quantity of tobacco cigarettes can be reduced by half, and cigarette may be shorter. Means restricting the airflow can be is formed by the set of holes of different size or corrugated sections with longitudinal holes along the side of the cigarette. In U.S. patent 4638819 described a ring that is placed on a cigarette and move along it in the process area to control the speed of free burning cigarettes and reduce side smoke. The ring is made of a rigid material, preferably metal, which causes considerable staining and because of the different diameters of cigarettes cannot reliably provide the desired degree of reduction side of the smoke and the time of clearing.

Other systems designed to control side smoke described in WO 95/34226 and in U.S. patent 4685477; 5592955 and 5105838. In these sources described the various tubular structures, in which is placed the tobacco element, to minimize adverse selection smoke.

In cigarette design has been used in various types of ceramic parts, including an insulating tube for cigarettes, and an insulating tube for devices, generating cigarette smoke. In U.S. patent 4915117 described a thin sheet made of ceramics, which replaces the cigarette paper to reduce the amount of organic matter released during the combustion of conventional cigarette paper. Insulating ceramic liners are described in U.S. patents 5105838 and 5159940. In U.S. patent 5105838 described cigarette with fine tobacco rod, comprising circumferentially about 12.5 mm Insulating ceramic sleeve has a low thermal conductivity and made aristoi. To reduce the allocation side of the smoke of burning tobacco rod speed free combustion is reduced through the use of wrappers with low porosity, is placed around the porous ceramic member, the wrapper has a permeability of less than about 15 units of Coresta.

In U.S. patent 5592955 described non-combustible, porous membrane reuse for storage and retention stud Smoking material before, during and after Smoking.

The reduction in allocated from the device side of the smoke is provided by an outer wrapper shell, which has a permeability of less than 40 units Coresta, and the radial thickness of the shell is from about 0.25 to 0.75 mm, the Wrapper determines the overall porosity of the device and thereby controls the speed of free burning cigarette and reduces the adverse selection of smoke between puffs. The device has a breathable cap on the open end of the tube. Fireproof shell may contain a metal ribbon, which serve as heat sinks to reduce the velocity of the free burning of the tobacco rod.

In Smoking devices, such as filters, tobacco, especially cigarette smoke was used catalytic material for converting the main components of smoke, usually by oxidation, as long as the ANO in U.S. patent 3693632, the UK patent 1435504 and published applications, European patent EP 107471 and EP 658320. The catalysts were also introduced into a cigarette paper, which is used to wrap the tobacco, as shown in canadian patent 604895 and in U.S. patent 4182348 and 5386838. In tobacco and in cigarette filters were introduced adsorbing materials, such as zeolites. Zeolites adapted for this application, as described in the application EP 740907, where such zeolites have a pore size in the range of 5-7 angstroms.

The applicant has made a substantial contribution in this area, as described in U.S. patent 5462073 and 5709228 and publications WO 96/22031; WO 98/16125 and WO 99/53778. Fireproof system described in each of these published patents and applications, designed for control systems with the side of cigarette smoke. In particular, in the international application WO 99/53778 described material for the processing side of cigarette smoke, which used the combination of materials with well-developed ERP system significantly above 200 units of Coresta, and oxygen-containing component capable of giving oxygen. Although these different devices with varying degrees of success fought side by smoke from a burning cigarette, different variants of the present invention offer a fireproof material that can tolerate the side of cigarette smoke unexpectedly better without the need for highly porous material to provide about the offered speeds of free burning. More specifically, the present invention relates to a simple in the manufacture of fireproof material for the processing side of the smoke, having a porosity less than about 200 units of Coresta.

The present invention in its various embodiments, leads to a significant reduction of side smoke. Unexpectedly it was found that the reduction side of the smoke can be achieved through the use of non-combustible material with a porosity less than about 200 units of Coresta and preferably less than 30 units of Coresta. This processing material includes a composition for treatment of side smoke, containing, in combination, a metal oxide oxidation catalyst for storage, and return of oxygen and essentially non-combustible finely dispersed, porous, particulate, powder additive to the catalyst.

Fireproof material can be shaped spatial form of sheet, wrapper, paper, etc. Such molded handles the material can be shaped in the form of a tube that is placed on the cigarette paper is essentially in contact with it, while the processing material can be wrapped around a cigarette and to be essentially in contact with the cigarette paper, or this material may replace the traditional cigarette paper. This fireproof material provides acceptable speed free gorini the traditional cigarettes, at the same time minimizing or virtually eliminating the visible side of the smoke.

Additive catalyst can be selected from the group consisting of clays, essentially non-combustible milled fibres, monolithic materials, mineral-based, essentially non-combustible activated carbon, zeolites and mixtures thereof.

The addition of the catalyst may be any suitable essentially non-combustible powder such as clay, carbon materials, such as crushed porous carbon fiber, ceramics, for example milled porous ceramic fibers and porous particles with high surface area. In this regard, the most preferred additive to the catalyst is essentially non-combustible sorbent material with a large surface area such as activated carbon or zeolites. In the most preferred embodiment, the sorbent materials are zeolites, in particular hydrophobic zeolites. Zeolites are particularly preferred in combination with a catalyst based on cerium.

The composition for treatment of side smoke can be applied in different ways. This composition can be used as a filler in the manufacture of fireproof material, which is impregnated non-combustible material, or as a coating(I) or layer(s) on the outer or inner surface of the fireproof m the material. The resulting material for the processing side of the smoke may have a porosity of less than 200 units of Coresta. The preferred porosity is generally lower and ranges from about 0.5 to 30 units of Coresta. This material can be used as a multiple wrap. This material can be applied as outer wrappers around cigarettes traditional cigarette paper.

The composition for treatment of side smoke can be applied in the form of a coating on either side or on both sides of the wrapper of the cigarette with multiple (usually double) wrapper, or be entered in the material, or can serve as a filler in the manufacture of material for a single or multiple wrapper of cigarette paper. In the case of the double wrapper composition for treatment of side smoke in one embodiment, may be located between the two wrappers. In another embodiment, this composition may be coated side of the wrapper adjacent the tobacco rod, and you can provide different amounts of the composition between the two wrappers. In yet another variant with a double wrap the composition for treatment of side smoke can be applied on both sides of the wrapper, placed on the tobacco rod, possibly, in different quantities. The second wrap can be used as an additional wrapper around the first wrap. It was found that for ballegooyen selection of side smoke catalyst and additive must be used together. These two components can be mixed as a filler, for example, in the manufacture of fire-resistant material. Alternatively, when used as coating the catalyst and additive also mixed, usually in the form of a suspension, and in this form are applied on a non-combustible material. As for the preferred options and, in particular, the joint application of cerium with zeolite, these materials can be applied in the form of separate contacting of thin layers for the formation of a multilayer coating. Such layers can have a thickness less than the thickness of conventional cigarette paper and due to their close contact to work as if they were combined and mixed.

Fireproof material for the processing side of the smoke, having a porosity less than about 200 units of Coresta, when used for the treatment of tobacco smoke according to the present invention provides very significant unexpected advantage, especially against a side of smoke. This machining material can have the form of a tube, placed in a cigarette paper cigarette and are essentially in contact with it, this material may be wrapped around the cigarette paper of a cigarette and to be essentially in contact with it or this material can replace the actual cigarette paper cigarette. When machining material has the form of a tube, placed in a cigarette paper cigarette and are essentially in contact with it, or wrapped around a cigarette paper cigarette and is in contact with it, this design allows the use of traditional cigarettes, which when we smoke are the usual rate of free burning. The reference to the normal or traditional cigarettes means kommercheskoye cigarettes, containing tobacco rods with conventional stuffing and traditional varieties of tobacco, fillers and other Tobacco rod is surrounded by a traditional cigarette paper with normal porosity in the range of 5-50 units Coresta, and sometimes up to 110-120 units Coresta.

Cigarette can have a traditional filter, which is attached to the cigarette or the usual way, or connect with the machining material of tubular shape, which is then covered tobacco rod in a conventional cigarette paper. Traditional cigarettes have a normal speed of free burning from about 3 to about 5 mm/min, provided that the stuffing is from about 0.20 to about 0.26 g/cm3. Traditional cigarettes, at least North American, have a circumference of from about 20 to 30 mm, usually from about 23 to 27 mm, and the length of the tobacco rod at least about 40 mm, and preferably about 55 mm, about 64 mm and 74 mm, which creates an acceptable resistance to tightening. Cigarette filter has a length of from about 15 mm to about 35 mm

Cigarettes can be Smoking cigarettes manufactured or can be a tobacco rod, which cannot be directly smoke. According to one aspect of the present invention neweconomy rod becomes smoked when he put the paper with getting to the satisfactory cigarettes, or the paper is inside the tube processing material and inserted in the tobacco rod.

When machining material replaces itself cigarette paper in the cigarette, this allows the use of the above-described conventional cigarette without the usual paper, and which when Smoking is illuminated at normal speed free combustion. For example, the normal or traditional cigarette has a tobacco rod with traditional stuffing with traditional tobacco, fillers, and other Tobacco rod is surrounded by a material according to the invention. The cigarette in the usual way attach a traditional filter. Such a cigarette, at least in North America, has a circumference of from about 20 to 30 mm, usually from about 23 to 27 mm, and the length of the tobacco rod at least about 40 mm, and preferably about 55 mm, about 64 mm and 74 mm, which creates an acceptable resistance to tightening. Cigarette filter has a length of from about 15 mm to about 35 mm

The material according to the invention due to its proximity to the burning site is able to control the allocation side of the smoke with a very compact structure. Previously cigarette device, providing the usual speed of free burning, were very cumbersome, because the tube had a large cavity, and the tube was located at a distance from cigarettes, and such devices nor to the eat was not like a regular size cigarette. Attempts to control the selection of side smoke more compact devices traditional size led to using more subtle cigarettes to get the gap between the cigarette and the pipe. This could cause the smoker to change the brand of cigarettes, to use such a device and, moreover, could change the taste and flavor of cigarettes.

Machining material according to the invention has the advantage, particularly cigarettes, which allows the smoker to use cigarettes of your choice in the tubular structure or to buy familiar varieties of cigarettes wrapped in the material according to the invention with conventional cigarette paper or without it. Although the processing material according to the invention can be used in combination with other types of Smoking products, for example, pipes and filtration devices for General filtration of tobacco smoke from the air, its most important application is the use in cigarettes, cigars and other Smoking articles having an elongated shape. Machining material can turn around cigarettes a standard cigarette making machines, it can be used instead of the traditional cigarette paper, when cigarettes are produced in standard cigarette making machines or the material can forsirovatsya tube in which is inserted a cigarette and in which the inner surface of the tube in contact with the cigarette. Machining material allows you to smoke traditional cigarettes the usual conventional manner, ensuring the normal flavor and aroma and creating minimal, if at all any additional scent. These symptoms are especially pronounced when the cigarette is lit with the usual speed of free burning. Machining the material is non-combustible, easily recyclable and has no harmful impact on the environment, since it can be created from inert materials, such as ceramics, clay and other suitable binder and reinforcing materials. The processing material can be made so that it had a relatively low external temperature, to ensure improved safety performance. Collected cigarette has a small weight and at the open end is easily ignited. Although this option is not preferred, the tube can be adapted for reuse when it is inserted next cigarette instead of the one that was smoked.

The efficiency of processing of the material increases due to the fact that he is very close to the cigarette paper or the tobacco or in contact with them. Machining material due to its design the most is preferably essentially adjacent the burning coal of the cigarette to intercept, capture by absorption or adsorption, or both, and for processing the various components of the side of the smoke, leaving a burning coal of the cigarette, which is free from cigarette paper and tobacco rod. It should be understood that absorbed only those components that have sufficient affinity to the processed material. Other materials, such as highly volatile gases can pass through the material is not absorbed them. However, such gases can be oxidized in the reaction zone of the material, and in the presence of a catalyst such oxidation reactions are accelerated. Machining material having the form of a tube, placed in a cigarette paper cigarette and contact with it or wrapped around a cigarette paper cigarette and in contact with it, or replacing the cigarette paper, allows the cigarette to burn in the usual way, without burning the material according to the invention. However, it should be noted that the processing material may have such a structure that while Smoking its structural strength decreased, allowing you to crush the cigarette before it is smoked to the end.

Modified machining material can be used for cigarettes"cigarettes, which are usually sold in nevicurative form, but when filling in the cartridge can be smoked. For example, on the inner side of the processing material in sheet form can be applied to cigarette paper, twist the tube, insert the tobacco rod, for example, described in canadian patent 1235039, and get ready to smoke a cigarette. The processing material may also be used on non-standard cigarettes, for example, with a modified cigarette paper, which reduces the speed of free burning cigarette. Although cigarette with a reduced speed of free burning are not preferable in certain cases it may be necessary in such devices, even if the taste and flavor will be different.

In accordance with a variant implementation of the invention, the first active component in the inventive material is additive (sorbent material)capable of selectively absorbing components side of the smoke emitted a burning coal of his cigarette. The second active component is a metal oxide catalyst for storage, and return of oxygen, which performs a dual function: releases the oxygen at temperatures of free burning next to a burning coal of his cigarette and works as an oxidation catalyst. This released oxygen performs at least the following functions:

i) compensates reduced the claimed material is the speed of diffusion of oxygen to the burning of coal, maintaining the normal speed of free burning cigarette, and

(ii) sposobstvuyushaya component side of the smoke.

The additive can be essentially any non-combustible fine porous material in the form of particles, which does not affect the taste and smell of the primary smoke and does not produce any undesirable smells in the side of the smoke. Additive physically stable at high temperatures at the burning coal of his cigarette. The Supplement has a large surface area, typically greater than 20 m2/, so that the particles had a surface, they must be porous. Preferably, the porous additive has pores with an average diameter of less than 100 nm (1000 angstroms). More preferably, the pores have an average diameter of less than 200 nm (200 angstroms), and even more preferred pores with an average diameter of from 0.5 to 10 nm (5-100 angstroms). In the case of materials based on zeolite pores have an average diameter of from 0.5 to 1.3 nm (5-13 angstroms).

Preferably, the average particle size of the additive was less than 30 μm, more preferably less than 20 microns and most preferably from 1 to 5 μm. Fireproof materials may be porous clay of different categories, widely used in the production of cigarette paper, such as bentonite clay or activated clay with a large surface area. You can use non-combustible carbon materials, including crushed porous carbon fibers and particles. As a porous monolithic mA the materials on the basis of minerals can be used metal oxides, including zirconium oxide, titanium oxide, oxides of cerium, aluminum oxide, such as alumina, metal oxide fibers, such as milled Zirconia fiber, and other milled porous ceramic fibers and mixtures thereof, such as zirconium-cerium fibres. As for cerium oxide, it was found that he is able to work fine as an additive and as a catalyst, storing and giving oxygen. Other additive materials are materials with a large surface area such as activated carbon and zeolites.

The additive may also contain sorbent materials with a large surface area, which is fireproof, fine particles, such as activated carbon, molecular sieves, such as zeolites and amorphous materials, such as silicon dioxide and aluminum oxide, etc. Most preferred are zeolites, such as silicate zeolites, X-, Y -, and L-zeolites, faujasite (faujasites) ((Na2,Ca, Mg)29[Al58Si134O384]· 240 H2O; cubic.), β-zeolites (Nan[AlnSi64-nO128] when n<7; tetragonal), mordenite zeolites(Na8[Al8Si40O96])· 24H2O; orthorhombic) ZSM-zeolite (Nan[AlnSi96-nO192]~16 H2O c n<27; orthorhombic), and mixtures thereof. The preferred zeolites are hydrophobic the zeolites and moderately hydrophobic zeolites, which have affinity to hydrophobic and moderately hydrophobic organic components such side smoke. Zeolites have a structure with a high porosity, which allows high selectivity to adsorb and absorb the components side of the smoke. This porous structure is mainly composed of macropores between particles and micropores inside the particles, which depart from the macropores. It is believed that the captured components in the macropores and the micropores in the presence of cerium oxide or other suitable oxidation catalyst at a high temperature of a burning cigarette is converted to the oxidized substances that remain in the sorbing material or allocated in the form of invisible gases having a substantially reduced content of tar and nicotine, so side smoke is invisible or allocation goes to the lowest acceptable level.

Zeolites can be characterized by the following formula:

MmM’nMp[a AlO2·b SiO2·c TO2]

where M is a monovalent cation

M’ is a divalent cation,

M’ is a trivalent cation,

a, b, c, n, m and p are numbers that reflect the stoichiometric ratio, and

s, m, n or p may be zero

Al and Si - tetrahedrally coordinated aluminum atoms and silicon, and

T - tetr edralin coordinated metal atom, able to replace Al or Si,

where the ratio b/a of the zeolite or zeolite like material has a value from about 5 to about 300, and the size of the micropores of the zeolite is in the range from about 0.5 to 1.3 nm (5-13 angstroms).

You can use different types of sorbent material. This is especially true for various classes of zeolites, which can be specially created for the selective adsorption of materials with high boiling point, with an average boiling point and low boiling point. This can lead to layers of zeolite compositions, where the cerium or other suitable catalyst provided by the present invention, preferably dispersed in all these layers. Then these layers can be connected with a tube or wrap with a binder or adhesive, which may be, for example, polyvinyl acetate, polyvinyl alcohol, starch and casein or soy proteins, and mixtures thereof.

Oxidizing the metal oxide catalyst, storing and giving oxygen, is introduced into the processing material or applied on at least one surface of the material. Oxidizing the metal oxide catalyst, storing and giving oxygen, preferably is a metal oxide having multiple oxidation States. It should be understood that the catalyst may be a precursor of a metal oxide, the cat is who when the temperature of a burning cigarette is transformed into a metal oxide, capable of catalyzing oxidation reactions. The metal oxide is most preferably selected from transition metal oxides and oxides of rare earth metals and mixtures thereof. Transition metal oxides can be selected from the group of metals containing metals IVB, VB, VIB, VIIB, VIII and IB and their mixtures. The preferred oxides of metals of the transition groups are oxides of iron, copper, silver, manganese, titanium, zirconium, vanadium and tungsten. The oxides of rare earth metals can be selected from the group consisting of oxides of scandium, yttrium and lanthanides.

Oxidizing the metal or metal oxide catalysts can be used in combination with oxidizing metal oxide catalysts, storing and giving oxygen. Such oxidizing metal catalysts include noble metals, metals of groups IIA and IVA, and mixtures thereof. Examples are tin, platinum, palladium and mixtures thereof.

Metal or metal oxide oxidation catalyst can be used together with cerium oxide, and metal or metal oxide selected from the group consisting of oxides of noble metals, transition metals, rare earth metals, metals of groups IIA, IVA, and mixtures thereof. Specified by the selected metal or metal oxide is platinum, palladium, copper oxide, iron oxide, magnesium oxide, silver oxide is whether their mixtures.

Preferred oxidizing catalyst, storing and giving oxygen, oxide-based metal lantanoides group, is the catalyst based on cerium and, in particular, cerium oxide. This catalyst not only works very well, accelerating the oxidation of the captured organic materials, but also performs well desired additional function storage, and return of oxygen in an oxygen-free environment. Catalytic processing material in the form of cerium oxide (CEO2in cold condition capable of storing oxygen, but when the temperature goes dioxide, cerium (CE2About3), releasing oxygen. As the burning coal of the cigarette is moved along the tube of the declared material, catalytic processing material emits oxygen at elevated temperature to maintain the normal velocity of the free burning cigarette. In addition, the selected oxygen also supports the catalytic oxidation of the captured component side of the smoke.

As stated above, oxidation of the metal oxide catalyst, storing and giving oxygen may be in the form of a metal oxide or in the form of a precursor of a metal oxide, which, if the temperature of the burning cigarette is transformed into a metal oxide and begins to perform the function of a catalyst. The cerium precursor cat who lyst may be a salt of cerium, for example, cerium nitrate or other dispersible forms of cerium, which is applied in solution or in the form of Zola on the sorbent material and converted into cerium oxide at a high temperature of the burning cigarette in order to demonstrate the catalytic activity. To simplify the description of the present invention, the term "catalyst" refers to any catalyst precursor.

A catalyst such as cerium oxide, used in combination with the additive material. It was found that when these two materials are used separately from each other or in separate contiguous layers, their ability to control the allocation side of the smoke is greatly reduced. However, in certain cases, you may achieve some control of the allocation side of the smoke. Preferably the catalyst is essentially related material additives. This can be achieved by mixing catalyst particles in the additive material, by contact of the layer of additive material with a layer of catalyst by depositing a catalyst on a Supplement or by impregnation of the catalyst or porous surface material additives to obtain desired characteristics of the control side of the smoke. It should be borne in mind that in addition to a combination of oxidation catalyst and additives can be used and many other components. The stage is leitlinie additives can be used to intensify further processing side smoke or to change other characteristics of the cigarette. Such additional additives may podmahivat in the processing composition or used in other places to the design of cigarettes, of course, provided that such additive will not adversely affect the ability of the processing composition to treat side smoke. In specific embodiments, the composition can be mixed in various ways that provide mixing of cerium with the additive material. For example, the additive material may be sprayed or add in a solution of cerium salt such as cerium nitrate or cerium Sol, for impregnation of cerium in the material additives. The cerium oxide may be prepared as a separate fine powder, which is mixed with fine powder of the additive. Particularly preferably, the powders had an average particle size less than 30 microns and preferably less than 20 microns and most preferably from about 1 μm to 5 μm to ensure thorough blending and mixing materials.

The General rule is to select the size of catalyst particles and their surface area professionals in this field know the surface area of the selected catalyst should be such that the active area of the catalyst were available migratory components side smoke. This may lead in some embodiments, the particle size of the catalyst will be the pain of the e 30 μm, if the catalyst particles are properly allocated to achieve the required degree of oxidation of the component side of the smoke.

Unexpectedly it was found that the cerium oxide is one of the new oxides that can perform both functions, namely to work as oxidation catalyst, storing and giving oxygen, and also as an additive. Porous particles of cerium oxide can have a surface area and particle size required for supplements. The cerium oxide used in the manufacturing of the composition in the first number as the catalyst, and the second number as an additive. Such amount of cerium oxide in General correspond to the amounts used as the catalyst and as an additive in accordance with other objects of the present invention to provide a complete load.

Cerium can be represented in the form of dispersed solution, such as a Sol of cerium oxide, or in such form and be applied to the additive material, such as zeolite. It is then dried and calcined to obtain cerium oxide on the surface of the material additives. When the particles of cerium oxide attached to the surface of the additive, for example, to the surfaces of the zeolite, the average particle size can be less than 1 μm. The relative amount of cerium oxide, attached to the zeolite may be in the range of from about 1% to 75% by weight of the total amount the VA cerium oxide and zeolite. The preferred relative amounts of cerium oxide, attached to the zeolite may be in the range of from about 10% to 70% by weight of total cerium oxide and zeolite.

The preferred method of manufacturing a composite product, i.e. cerium oxide attached to the surface of the zeolite described in application for U.S. patent, which is considered in parallel, entitled "Method of manufacturing a coated metal-oxide microporous materials", filed September 14, 2001, the contents of which are incorporated into this description by reference.

Although in the above application provides a detailed description of the production of the combined product, check that according to the method of manufacture of catalyst, in the form of particles, the zeolite material, coated with cerium oxide containing at least 1% by weight of cerium oxide, deposited on the outer surfaces of the particles of the zeolite material of the total equivalent content of cerium oxide and zeolite. According to one of the objects of the method involves, in General, stage:

i) connection a certain amount of a colloidal dispersion of hydrate of cerium oxide with a compatible zeolite material in the form of particles to form a suspension, and the amount of the colloidal dispersion is sufficient to ensure that after heat treatment at stage ii) bol is e 20 wt.% cerium oxide, particles of the zeolite material has an average pore size of less than 20 angstroms, and the colloidal dispersion has an average particle size of at least 20 angstroms;

ii) heat treatment of the first suspension at a temperature lower than about 200aboutAnd then at a temperature higher than about 400aboutWith, for attaching the obtained cerium oxide to the outer surfaces of the zeolite particles, to obtain a free flowing powder.

This product is manufactured by a company AMR Technologies, Inc. Toronto, Canada. Alternatively, this method sorbent additive you can put in the cerium salt solution, dried and subjected to heat treatment to provide cerium oxide on the surface of sorbent material.

Oxidizing the metal oxide catalyst, storing and giving oxygen that can release oxygen at elevated temperatures, usually above 300aboutC. it has been Unexpectedly discovered that the selected oxygen works exactly where it's needed - in an oxygen-free environment around the burning ember. Although machining material having a porosity less than about 200 units of Coresta and usually less than about 30 units of Coresta, allows a small amount of air to diffuse to the burning of coal, oxygen allocated oxidizing the metal oxide catalyst, storing and giving oxygen, enough to keep usually the second speed of free burning. It was completely unexpected. Handles the material with a porosity less than about 200 units of Coresta and usually in the range of from about 0.5 to 30 units of Coresta with a combination of oxidizing the metal-oxide catalyst, storing and giving oxygen, with the additive material, turned out to be sufficient. Oxidation of sorbed component side of the smoke passes with sufficient speed to visible components were not allocated from this material. Any components that may be visible at the exit of the material in the atmosphere is converted into invisible components, or remain trapped in the material by sorption. The processing material may be used in the form of a two-layer or multi-layer wrapper. The processing material may be applied in the form of the outer wrapper on a cigarette with conventional cigarette paper. In addition, it should be noted that depending on the porosity of some combination of catalyst and additives work better than others. Fireproof machining material in combination with an oxidizing the metal oxide catalyst, storing and giving oxygen, and the additive may contain any suitable essentially non-combustible paper, which does not affect the taste and aroma of the main smoke and does not give undesirable odor side smoke. This fireproof the material, formed in the paper having different porosity may contain clay of different categories, usually used for the production of cigarette paper, such as bentonite clay or activated clay with a small surface area. Can also be used fireproof carbon material such as carbon fiber, and ceramic material, such as ceramic fiber. Fireproof paper is physically stable at elevated temperatures of the burning coal of his cigarette.

We offer fireproof machining material is preferably made in the form of a sheet with a thickness of about 0.04 mm to about 2 mm, but preferably not more than about 1 mm, the sheet can be made of standard continuous method of making paper without heat treatment, or methods associated with the heat treatment, as described in the aforementioned U.S. patent 4915117, the content of which is incorporated into this description by reference. Prepare a suspension containing inorganic fireproof active materials, fireproof fillers and other combustible organic materials. The suspension is formed into a sheet-predecessor, which is kept at elevated temperature for evaporation of organic matter and thereby creating a porous structure so that the sheet had a porosity less than about 200 units To the esta. Unlike fireproof high-porous material, the material having a porosity less than about 200 units of Coresta, to achieve a desired porosity requires lower concentrations of organics. In another embodiment, to obtain a fireproof declared material can be used very highly porous fireproof paper (with the number of Coresta more than 200). This fireproof paper with high porosity can be covered with the processing composition, filling the pores and the resulting material, which will have a porosity of less than 200 units Coresta. Further, low-porosity fireproof paper may be covered with the processing composition, filling the pores, which will lead to the production of a material with even more low porosity, for example from about 0.5 to about 30 units of Coresta.

It should be understood that it may be designed non-combustible material with a modified thick modified pore size, etc. to allow a certain number of secondary smoke to pass through the tube. This can be necessary if a smoker wants to feel faint smell of side smoke on the surface of the tube. Fireproof material preferably performed for a single use, after which the material is thrown away. This feature optimizes the design from the point of view of the thickness of the tube, as in a single administration for Arby side smoke required minimum thickness.

For manufacturing manufacturing material processing composition of oxidizing the metal-oxide catalyst, storing and giving oxygen, and supplements can simply be sprayed by standard methods on one or on both sides non-combustible substrate, which may be in the form of sheet, wrapper or paper. As shown in figure 1, the substrate 10 is transported in the direction shown by the arrow 12. The composition 14 is sprayed in the form of a suspension spray nozzle 16 on the substrate 10 to obtain a coating 18, which is dried on the substrate.

Alternatively, the composition can be ekstradiroval in the form of a film on the surface of both sides or on either side of a non-combustible substrate. As shown in figure 2, the device 20 for applying a film coating contains a suspension of the processing composition 14. The device 20 causes the thin film 22 on the substrate 10, which is transported in the direction shown by the arrow 12. The film is dried to obtain a coating 24 on the substrate 10. The coating can be applied and roll applicator 26, as shown in figure 3. The suspension containing composition 14 is applied layer on the roller 30. The blade 32 determines the thickness of the layer 34, which is then applied to the substrate 10 is transported in the direction shown by the arrow 12. Then the layer is dried to form a coating 36 on the substrate 10.

The composition may also b is to be impregnated on both sides or on one either side of a non-combustible substrate. Impregnation carried out covering the roller 24 in figure 4, and the resulting layer 36 on the substrate 10 passes in the direction of arrow 12 through the pinch rollers 38 and 40, which presses the layer of the composition to the substrate 10, thereby impregnarea components of the composition into the substrate.

The specialist will also be clear that for the manufacture of the material according to the invention can be used, and other coating methods, including methods of coating with the transfer. In these ways cover for the transfer of the composition from the sheet on the surface of the substrate may be used a sheet of Milara (Mylar™ ) or other suitable sheets. This type of application migration is used when the sheet substrate unsuitable for application of the composition roller due to the low physical strength of paper or similar material.

Another alternative is the introduction of processing composition in the process of manufacturing a fire-resistant sheet. The composition can be entered in the pulp in the form of suspension. As shown in figure 5, the processing composition in the paper pulp 42 is stirred by the agitator 44 for receiving the pulp in the tank 46. The pulp is transferred in the usual way and placed on a moving conveyor 50 in the form of a layer 48 for receiving the cigarette paper 52. In the processing composition is embedded in the finished material, which may be in the form of paper products the Oia. Another alternative is the placement of the processing composition between layers of non-combustible substrate for forming a double wrapper of cigarette paper tobacco rod. For example, the composition can be applied as shown in figure 1, i.e. by sputtering on the inner surface of the outer substrate or the outer surface of the inner substrate. After both substrates will be placed on the tobacco rod, the composition is in the form of a layer is enclosed between the two substrates. Each substrate may be half the thickness of conventional cigarette paper to double wrap slightly increased outer diameter of the cigarette, which will normally be processed cigarette making machines.

As shown in Fig.6, the tobacco rod 54 includes, for example, fireproof material, is used as the paper 10, wrapped around him with a coating 18 on the outer side of the paper. On the contrary, as shown in Fig.7, fireproof paper 10 may have a coating 18 on the inner side facing to the tobacco rod 54.

Another alternative is shown in Fig and, as shown above, is the placement of the cover 18 between fireproof paper layers 56 and 58. Paper 56 and 58 with the intermediate layer 18 can be formed as a single cigarette wrappers installed on the tobacco rod 54. Another in the version shown in Fig.9, where the tobacco rod is covered with a traditional cigarette paper 60. Over the traditional cigarette paper 60 is fireproof paper 52 in figure 5 has embedded in it the composition stated. It is clear that the paper 52 may be mounted directly on the tobacco rod 54.

The specialist will be clear that the above routes of administration of the composition for treatment of side smoke on or in the wrapping may vary depending on the load the wrapper and the number of wrappers used in the tobacco rod. For example, you can use two or more wrappers with different amount of composition applied on both sides of the wrapper, so that the number of tracks on one side has been reduced to facilitate the coating process.

It was unexpectedly found that with any of these combinations side smoke virtually eliminated. At the same time, the cigarette paper of a traditional cigarette, is shown in Fig.9 shows the common characteristics of education ashes, even if fireproof paper has a porosity less than about 200 units of Coresta.

As for the prototype devices, which provides a tubular material or wrap, placed on the cigarette, they on the outside of the tube is usually applied additional paper material to provide additional control over the diffusion of oxygen, which is advised to reduce the speed of free burning, and thereby, reduce side smoke. In contrast, the present invention provides a processing material in the form of a tube or wrapper, which allows traditional cigarette to burn with the usual speed of free burning and highlight side smoke in the usual way, including the smoke generated by the cigarette paper. In addition, the present invention provides a material that can replace the cigarette paper and allows the tobacco to burn with the usual speed of free burning and highlight side smoke in the usual way. This machining material effect on the components side of the smoke from outside cigarette paper or tobacco, if we are talking about replacing plain paper), regardless of the generation of the main smoke. This separation processing of smoke from the production of primary smoke ensures that the components side of the smoke does not fall into the main stream smoke, have no noticeable effect on the taste and aroma of the main smoke and do not create appreciable concentrations of substances that are not present in it, when cigarette vymeryaetsya freely. Components side smoke can absorb the proposed material to be processed and go outside into the atmosphere. The physical structure of the material there is nothing that would lead machined components and the resulting reaction products back into the cigar is fair tobacco, avoiding significant changes in the taste and aroma of the main smoke.

It should be noted that depending on the manner in which the processing composition is used and applied on a non-combustible substrate, may require different excipients and mixtures thereof, to facilitate a specific method of applying the processing composition. Such excipients include laminating materials such as polyvinyl alcohol, starch, carboxymethyl cellulose (CMC), casein, and other types of acceptable adhesives, different types of binding clays, inert fillers, brighteners, agents, viscosity modifier, an inert fibrous material such as Zirconia fiber and zirconium-cerium fibres, as described in the application U.S. "Zirconium metal oxide fibers", filed September 13, 2001, the contents of which are incorporated into this description by reference. Can be applied and agents promoting penetration, for transfer of the composition on a non-combustible substrate. For dilution of the composition with the formation of the suspension used diluents, for example water, which allow to apply the composition on a non-combustible substrate by spraying, watering, air scraper, using straps, doctor knife, by printing, using a size press, a method of knurling, slotted extrusion, p is the postponement of other ways.

The desired loading of the composition on or in the fireproof material is from about 2.5 g/m2to about 125 g/m2. The most preferred loading is from about 2.5 g/m2to about 100 g/m2. In weight percent, fireproof processing material may contain from about 10% to 500% by weight and most preferably from about 10% to 400% by weight from the processing composition. Although this is representative for a single wrapper, the specialist will be clear, these common boot can be used for two-layer wrapper, and the wrapper having more layers.

Composition to reduce the side smoke is usually used in the form of an aqueous slurry. The suspension can be introduced into the pulp non-combustible wrapper in the process of making wrappers, or applied to the wrapper in a variety of ways or impregnate in the wrapper in a variety of ways, as described above. The preferred average particle size in the suspension is from about 1 micron to about 30 microns, and most preferably from about 1 μm to about 5 μm. The preferred amount of catalyst is associated with the additive may be in the range of from about 1% to about 75%, more preferably from about 10% to about 70% and even more preferably from about 20% to 70% by weight of the total equivalent content to the of telesfora and additives.
