Abstract
A process for the conversion of carbon monoxide in synthesis gas mixtures to hydrogen and CO.sub.2 utilizes a catalyst which is active in the presence of sulfur compounds, and which comprises the oxides or sulfides of cobalt and molybdenum, supported on a shaped, relatively high surface area aluminous carrier. The carrier is stabilized by admixture with one or more rare earth metal oxides while the alumina is in the hydrated condition. The mixture of hydrated alumina and rare earth metal oxide is formed into a desired shape and calcined to convert the hydrated alumina to the oxide. Thereafter, the calcined, high surface area alumina is impregnated with the desired salts of cobalt and molybdenum and the impregnated catalyst is thereafter calcined and placed into service. The stabilized catalyst exhibits good activity at relatively low temperatures with synthesis gas mixtures containing sulfur compounds and retains its surface area and the aluminous carrier is not converted over to the alpha phase.
