Abstract
Small area (approximately 1 cm**2) rhenium and iron foil catalysts have been studied for CO hydrogenation reactions Rhenium produces primarily methane and showed lower activity than iron. The addition of submonolayer amounts of alkali decreased the overall rate of reaction and caused a selectivity change toward longer chain hydrocarbons on both metal surfaces. Oxidation of the surface usually caused a higher selectivity toward methane and a decreased rate of carbon buildup, but the overall rate of methanation remained relatively constant. The hydrogenation of carbon or CH//x fragments appears to be the rate-determining step in the reaction.
