A modern progress of industry and energetic indicated an expansion of fields of hydrogen using. Possessing high calorie content, considerable reactionary ability and small density, hydrogen is an irreplaceable component in chemical and power processes, and also in lifting device at the research of atmosphere and ocean.
With the appreciation of value of hydrocarbon raw material expediently on the base of electric power, produced on HES and АES in the "failure clock" of their exploitation, and also to get substances electric power of the wind, geothermal and ocean stations with high power-hungryness, to deliver them to the consumers and use for the production of hydrogen. Such chemical power substances can be alloys on the basis of aluminium, silicon and other elements, got from oxides of inorganic part of coals. Alloys are able at certain terms to displace hydrogen from water.
Effective another way of receiption of hydrogen is an electrolysis of coal-water slurries. From here a necessity appeared for development of appropriate reactionary equipment. Both reactors and electrolyzers must possess of minimum steel steel intensity. This requirement is executed at high speed of processes. For this purpose it is necessary to raise the temperature of reactive environments. Expediently also to eliminate a compressor for sending of the generated hydrogen to the consumer, i.e. processes in a reactionary equipment must be held at high pressure. Executing both these requirements and taking into account a strength properties of steels, from which makes the apparates, the processes of production of hydrogen were studied at the temperature of 70-460С and pressure from 0,1 to 20 МPа.
It is experimentally set that by most activity at reaction with water alumosilicic alloys possess with the admixture of the alkaline-landed metals (calcium, strontium and barium). The experienced data are generalized as equalization of Еrofeev, reflecting dependence of plenitude of reaction on time of reactionary surface. Comparison of activity of alloys is conducted at an equal temperature under reaching the reactionary surface of values equal to the surface of the dispergated substance in alkali of one or another alloy. Thus motive force of process was accept chemical potentials in this case. The found conformity to law submits to equalization of Gibbs-Folmer, in which the coefficient of proportion between speed of reaction and chemical potential depends on properties of alloys, temperature, pressure and geometrical sizes of reactors.
At the choice of optimal external of equipment environments except power descriptions of reactions information is needed about interphase heat-mass-transform. Experiments showed, that intensity of heat emission from the particles of alloys to water approximately the same as at evaporation of water in own pairs. The made model of calculation of apparates includes equalizations of formal kinetics, formal thermodynamics and criterion equalizations of heat-mass-transform. In the same order the calculation of electrolyzers is executed.
