The invention relates to the field of preparation of adsorbents and carriers with supported catalysts and can be used to prepare catalysts for various catalytic processes, in particular processes for the conversion of hydrocarbons (selective hydrogenation and oxidation, CO oxidation, epoxidation of ethylene and oxidative dehydrogenation of methanol to formaldehyde, the decomposition of hydrogen peroxide and other

Fiberglass materials intended for use primarily as a thermal and electrical insulating materials and fillers in the manufacture of fiberglass composites have long remained outside the sphere of interests of producers of catalysts. Some attempts to use silica woven materials for the manufacture of catalysts for neutralization of autowakeup were made in the 70-80-ies (the Japan patent No. 22145, 137752).

Over the last 10-15 years the interest in catalysts on fiberglass media increased dramatically: the effect on the properties of the catalysts of the original composition of the optical fibers, in some cases there is a higher activity of the metals deposited on glass compared to traditional media, which is explained by the presence of specific surface active centers formed by the interaction of ions IU the Alla with fiberglass. The following is not a complete list of processes, the catalysts are prepared on the basis of steklotkani media: production of sulphuric acid and nitric acid, the oxidation of ammonia (RF patent No. 2069584), the process of smelting reduction of aromatic nitro compounds to the corresponding amino compounds (patent RF №2156654), recovery of nitrogen oxides, oxidation of hydrocarbons (methane, propane, butane); alkylation of hydrocarbons, hydrogenation of hydrocarbons (RF patent No. 2143948), selective hydrogenation of acetylene and/or diene hydrocarbons, hydrogenation of vegetable oils and fats (RF patents №2109039, 2158632), the processing of hydrocarbons and petroleum products, hydrodenitrification water (patent RF №2133226), the production of formaldehyde from methanol, the catalytic heat generators; neutralizers industrial and vehicle emissions and thermal cleaning of exhaust air (patent RF №2161430). In some cases, the fiber is used as the sorbent (RF patents №2169612).

Over the past decade, the literature has reported detailed studies of physico-chemical properties of leached glass fibers of different composition deposited on these metals, as well as the influence of the media on the state of metal such modern techniques as transmission electron mi is roscope, X, NMR nuclei11In,27Al,23Na29Si133Cs and adsorbed molecules129Heh. This class of catalytic systems characterized by fundamental scientific novelty and the novelty of their technological applications. The main distinguishing features of silica steklotkani catalysts as new technical solutions are protected by patents of the Russian Federation No. 2069584, 2160156, 2250890, 2250891, 2252208.

It should be noted that the original fiberglass have a low specific surface area (up to 1 m2/g). For many processes, carriers for catalysts with such surfaces are not suitable, because the dispersion of the catalysts, especially platinum group metals, depend directly on the surface of the carrier. One of the methods of increasing the surface of the silicate glass fibre materials is a selective extraction (leaching) of them decrementing components dependent on temperature and processing time. The increase in the degree of leaching leads to increase in the number and size of the pores, and then a significant rebuilding of the internal structure. An important feature of some of fiberglass materials is the reduction of mechanical strength by increasing the degree of leaching. In addition, loss of strength increased in samples subjected to high temperature annealing to the to before, and after leaching. These circumstances have a negative impact on performance products fiberglass.

Another way of increasing the surface of the glass, allowing you to save all of its catalytic and operational benefits, is the modification of special compositions. Previously it was proposed to use the application on the bales of fiberglass, and later on fiberglass highly dispersed oxides, which either are themselves sorbents or catalysts (U.S. patent No. 4038214, Techno Jap. - 1992. - Vol.25. - N 9. - P.107), or serve as a dispersant substrate for more valuable catalytic materials, such as noble metals (U.S. patent No. 5552360, RF patent №2264858). While the application of the secondary carrier produced by the method of gilotinirovaniya from solution (Jap Techno. - 1992. - Vol.25. - N 9. - P.107), the bonding powder of the oxide silicate (Ecol. systems and devices. - 2006. - N 10. - P.48-50), aluminophosphate (RF patent No. 2139267) or organic binder (A.S. SU 934630). Describes the deposition of aluminum oxide from the corresponding gel on an inert granular carrier (patent RF №2378051).

Closest to the present invention is a method of increasing the surface of the glass and the carrier for catalysts obtained by this method (based Catalysts fiberglass but is of Italy I. Physico-chemical properties of silica fiberglass media / Lgema, Val, Obephen, EAACI, Try, Whitenose, Bismaleimide // Kinu. and Catala. - 2001. - V.42, N 5. - S-772). The method is based on the leaching of the original fiberglass to remove members of the fiberglass metal compounds. By the given data, the annealing leached fiberglass leads to an increase in specific surface area 1.5-1.8 times. However, the surface thus prepared media is very low (1.5-2.0 m2/g), which does not contribute to the dispersion of the applied active ingredients.

The aim of the invention is to develop a simple, environmentally friendly and inexpensive way of getting media on the basis of fiberglass catalysts for various processes without changing the composition and three-dimensional structure of the source materials. The received media combine advantages of fiberglass (such as temperature, the possibility of catalyst required geometric shape, providing a low aerodynamic resistance) and deprived of its main disadvantage is the small specific surface area.

The proposed method for the preparation of media includes single or multiple impregnation on capacity of aqueous solutions of modifying the predecessor of the in, which use crumpsall (colloidal crumpsall brand KS-TM, production LLC SITEK", Saint-Petersburg, THE 2145-004-12979928-2001), Sol of aluminum hydroxide (Hydrosol of alumina, mark "Aluminol And"production "STC "Compass", Kazan, THE 2163-007-61801487-2009), xinitrc aluminum (prepared by the method described in (M.M. Sychov, Inorganic adhesives, Leningrad: Chemistry, 1986)), or by applying an alcohol solution of tetraethoxysilane (TEOS, THE 6-09-3687-74) hydrolysis in water vapor at 70-80°C for 3 hours, followed by drying at 120°C for 1 h and calcination at 550°C for 4 h Single or repeated immersion in ethanol solution of tetraethoxysilane.

A distinctive feature of the proposed method is the formation on the surface of the fiberglass layers of silicon oxide or aluminum oxide from solutions of TEOS, Kremenets, alumets and oxynitride aluminum, thus increasing the specific surface and change the nature of the surface of the carrier, thereby extending the scope of applicability of the glass.
