Abstract

The effect of rhenium on the Co-based bimetallic catalysts prepared by various techniques on different supports was studied and were related to the structural effects to the activity/selectivity of these catalysts in CO hydrogenation. Direct evidence was obtained on the Re-Co bond formation. Rhenium increased reducibility of Co 2+. Kinetic data in the CO hydrogenation showed that rhenium promotes cobalt activity and the selective formation of higher hydrocarbon. Rhenium stabilized nanoparticles by interaction of ReO x with the support and increased cobalt oxide dispersion. Depending on rhenium location, it promoted enhanced rate and C 5+, while the presence of rhenium at the surface increased the hydrogenation/chain growth, thus higher CH 4 and C 2-C 4 selectivity. This is an abstract of a paper presented at the 229th ACS National Meeting (San Diego, CA 3/13-17/2005).
