FIELD: chemistry.

SUBSTANCE: invention relates to improved method of obtaining hydrogen by reaction of carbon-containing raw material with vapour and/or oxygen. Method of enriching synthesis-gas by hydrogen, with synthesis-gas including hydrogen, carbon monoxide and vapour, consists in conversion of carbon monoxide and vapour above catalyst. Synthesis-gas has molar ratio of oxygen and carbon from 1.69 to 2.25, with conversion of carbon monoxide and vapour being carried ou.300°C to 400°C t in conditions of high-temperature conversion, where synthesis-gas has temperature from 300°C to 400°C and pressure constitutes from 2.3 to 6.5 MPa. Catalyst contains in its active form mixture of zinc-aluminium oxide spinel and zinc oxide in combination with promoter in form of alkali metal, selected from the group, consisting of Na, K, Rb, Cs and their mixtures. Catalyst has molar ratio Zn/Al from 0.5 to 1.0 and content of alkali metal is within the range from 0.4 to 8.0 wt % counted per the weight of oxidised catalyst. Invention also relates to application of said catalyst in exploitation of reactor for conversion under conditions, in which synthesis-gas, supplied into reactor, has molar ratio of oxygen and carbon from 1.69 to 2.25, for suppressing formation of hydrocarbon byproduct.

EFFECT: elaboration of improved method of obtaining hydrogen by reaction of carbon-containing raw material with vapour and/or oxygen.
