GAS HYDRATES IN THE SYSTEM H2-CH4 - H2O AT PRESSURES OF 4.5 TO 220 MPa AND CONCENTRATIONS OF 0 TO 70 MOL H2

摘要

Hydrogen is likely to become the main energy carrier in the future because it is an available, non-toxic and a high-energy fuel. Pure hydrogen gas is required for fuel cells that can be used as basic "reactors" for obtaining electric energy in a hydrogen oxidation process. At the same time, various industrial methods for the production of hydrogen have been proposed, based on the interaction of hydrocarbons (in general methane) that is contained in natural gas, coke-oven gas and the gas obtained by oil treatment with water steam or incomplete oxidation of hydrocarbons. It is natural that the question arises how to isolate hydrogen from such gas mixtures. One method of separation and concentration of multicomponent gas systems is via gas hydrates. By this method components of the mixture can be crystallised as clathrates with associated isolation and regeneration of gases in pure form.
