Title: Catalyst for carbon monoxide conversion in sour gas

Patent ·
OSTI ID:5903618

A unique catalyst configuration permits the conversion of carbon monoxide in sour synthesis gas mixtures, such as coal gases, that contain sulfur-bearing impurities. The catalyst comprises known sulfactive metal oxides or sulfides supported on a shaped carrier. These active compounds are further promoted with an alkali metal compound and an oxide or sulfide of manganese. Combined in the proper ratio, the two promoters provide a synergistic effect on the activity of the catalyst that is enhanced beyond that of the singly promoted catalyst. The catalysts are active at relatively low temperatures of less than 500/sup 0/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.
