Cobalt-molybdenum thin film catalyst

摘要

A thin film catalyst structure is described for use in hydrodesulphurization of gaseous hydrocarbon mixtures. The catalyst is formed starting with an aluminum substrate having an oxide surface layer and thin films of metallic cobalt and molybdenum are sequentially deposited on the aluminum oxide layer. The films of metallic cobalt and molybdenum are calcined and then reduced and sulphided to form a sulphided thin film catalyst structure having improved hydrodesulphurization properties.
