The invention is intended for the chemical industry and energy and can be used to obtain energy in transportation, residential heating systems in extreme conditions. Flameless fuel contains 30-33% solution of hydrogen peroxide and silver oxide as a catalyst. In a metal reactor was placed a silver oxide. Serves 30-33% solution of hydrogen peroxide. In the instant reaction of the formed gas-vapor mixture high pressure, consisting of water vapor and oxygen, and releases a significant amount of heat. To increase the number of gas-vapor mixture in an aqueous solution of hydrogen peroxide, you can optionally enter atomistically ammonium. In this case, the gas-vapor mixture further comprises nitrogen. The invention allows to increase the service life of the engine and to simplify design, increase efficiency, eliminate environmental pollution. 2 C.p. f-crystals.
The invention relates to the field of energy and can be used on different types of transport and heating systems of residential buildings and heating man in the world is in, methane and other hydrocarbon compounds. In addition, the quality of jet fuel used is hydrogen peroxide in a mixture of methane and hydrazinehydrate (,Remy. The course inorganic chemistry. So 1. - M.: Mir, 1972, S. 71 and 72).
Hydrogen peroxide under normal storage conditions practically stable in the pure state and in aqueous solutions. But in the presence of certain substances, such as platinum, silver, manganese dioxide, it decomposes to form water and oxygen, while also stressing about 24 kcal per 1 mol of heat.
It is also known that the oxide of silver, Ag2O decomposes into pure hydrogen peroxide, losing its oxygen and turning into metallic silver, Remy. The course inorganic chemistry. So 2. - M.: Mir, 1974, S. 394, 398). Outside solutions it decomposes at 300°also with oxygen. In water, it is practically insoluble (chemist's Handbook. So 2. L.-M.: Goskomizdat, 1951, S. 200, 201.).
It is known that water vapor at a temperature of about 300°C has a pressure equal to eighty atmospheres (see, Remy. So 1. S. 64).
The hydrogen peroxide in the interaction with a number of catalysts (chemical substances) capable of decomposition into its constituent elements without access of air to obrai hydrogen under certain conditions allocates 800 kcal of heat and forms about 1.35 cubic meter of water vapor and molecular oxygen. Under normal storage conditions, it is practically stable.
Such catalysts as potassium permanganate, metals as palladium and platinum, accelerate the decomposition of hydrogen peroxide. But most of them produces by-products (waste), adversely affecting the material of the engine or heating device, or pollute the environment with harmful substances.
Known flameless fuel containing a concentrated solution of hydrogen peroxide and the catalyst is potassium permanganate (U.S. Pat. RU # 2183285, CL F 02 To 9/42, 10.06.2002). The disadvantages of the known flameless fuel are insufficient heat and waste polluting the environment.
The invention solves the problem of the increase produced by the reaction heat and avoid pollution.
This is achieved by flameless fuel contains 30-33% solution of hydrogen peroxide and silver oxide as a catalyst.
The oxide of silver is devoid of these shortcomings. In the process of a chemical reaction with the hydrogen peroxide solution and many compounds does not change its properties. It practically does not dissolve the RA contact with one liter 30-33%-aqueous solution of hydrogen peroxide breaks it, turning into a gas-vapor mixture having a pressure of about 15 atmospheres and a temperature above 200°C, almost no rachodes a long time.
Despite the fact that the number of vapor phase at an expense of 1 l 30-33% hydrogen peroxide solution is slightly higher than the amount of steam and gas occurring in the decomposition of 1 liter of hydrogen peroxide, the catalyst allows under other equal conditions to reduce the consumption of hydrogen peroxide three times.
It should be mentioned that less concentrated aqueous solutions of hydrogen (below 30%) have a lower rate of decay is independent of the quantity of oxide of silver, and more concentrated lead to the fact that in the gas-vapor phase greatly decreases the amount of water vapor, which is the main carrier and the driving force flameless fuel. We should not forget that the formed elements after splitting aqueous solution of hydrogen peroxide in the proper cooling of the newly formed pure water and oxygen, which in extreme cases (when the work of explorers, divers and underground specialists) so the right people. Naturally, when spending flameless fuel as a motor, CIS silver is placed on the bottom of a metal reactor, which serves 30-33% aqueous hydrogen peroxide solution (periodically or continuously). When this chemical reaction proceeds instantaneously with considerable evolution of heat and formation of water vapor and oxygen under pressure of our proposed scheme:
3.2 kg+0,48+1,0=3.2 kg+1,25+0,23.
If the net impact of hydrogen peroxide on silver oxide latter moves in metallic silver, in this case this does not happen. Due to the release of large quantities of water vapor, nitrous silver remains unchanged, that is, not rachodes, serving as a catalyst (the carrier of oxygen).
According to us the reaction of 1,5 l of this solution immediately formed 2.5 m3water vapor and 200 l of oxygen with a pressure of about eighty atmospheres. This is enough to cause the rotation of any engine. The speed of traffic is directly dependent on the flow rate of the solution and its concentration.
With the aim of increasing the number of gas-vapor mixture in an aqueous solution of hydrogen peroxide, you can enter atomistically am case presents us the reaction proceeds according to the scheme
1 kg+3,2+0,9+0,48=3.2 kg+1.8 to+0,23+0,37.
In this case, in addition to water vapor and oxygen, optionally allocated free nitrogen.
We offer flameless fuel has several advantages: increases the service life of the engine, greatly simplifying its design; reduced to a minimum the cost of manufacture of the motor; does not require air flow, eliminating the need to use the ignition system; not pollute the environment with carbon dioxide; it greatly increases the efficiency of the engine.
The only drawback we offer flameless fuel is a bit higher cost compared to gasoline. However, hydrogen peroxide can be produced from nadkarni acid on the surface of the Earth, and not in its depths.
