Title: In-situ infrared study of CO hydrogenation over silica- and alumina-supported ruthenium and silica-supported iron

Journal Article · · J. Catal.; (United States)

An in-situ infrared study of CO hydrogenation over silica- and alumina-supported ruthenium and silica-supported iron detected surface species containing only carbon and hydrogen and CO species during the reaction of carbon monoxide with hydrogen at up to 573/sup 0/K. On ruthenium, long-chain saturated hydrocarbons formed below 473/sup 0/K which decreased with increasing temperature. They formed groups of one (or very few) CH/sub 2/ and/or CH/sub 3/ groups at higher temperatures, which were identical to the hydrocarbon species on iron. The data supported a mechanism of initial surface carbide formation which produced methane on total hydrogenation and surface CH/sub 2/ or CH/sub 3/ species on partial hydrogenation which may then participate in chain growth. Hydroxy carbene or formyl species were not detected.
