ABSTRACT:
A process is disclosed for the conversion of carbon monoxide in sour synthesis gas mixtures in the presence of a catalyst which is active in the presence of sulfur compounds. The catalyst comprises known sulfactive metal oxides or sulfides supported on a shaped carrier. The catalytically active oxides or sulfides are doubly promoted with an alkali metal compound and an oxide or sulfide of manganese. The two promoters combined in proper ratio provide a synergistic effect on the activity of the catalyst which is enhanced beyond that of the singly promoted catalyst. The catalysts are active at relatively low temperatures of less than 500.degree. F., even in the presence of sulfur compounds. The equilibrium for the conversion of steam and carbon monoxide to hydrogen and CO.sub.2 is favored at lower temperatures.
