摘要
FIELD: chemistry.;SUBSTANCE: invention relates to catalysts. Described is a catalyst for use in a high-temperature shift reaction, which, in its active form, contains a mixture of a zinc-aluminium spinel and zinc oxide combined with an alkali metal selected from a group comprising Na, K, Rb, Cs and mixtures thereof, said catalyst having molar ratio Zn/Al ranging from 0.5 to 1.0, and alkali metal content ranging from 0.4 to 8.0 wt % with respect to the weight of the oxidised catalyst. Described is a method of enriching a synthesis gas mixture with hydrogen or carbon monoxide by reacting said synthesis gas mixture with the catalyst described above.;EFFECT: high catalyst activity.;8 cl, 8 tbl, 31 ex
