Carbon Monoxide Hydrogenating Characteristics of Various Catalysts Containing Rhenium

Abstract

Carbon monoxide hydrogenating characteristics of A-, B- and C-series catalysts containing Re have been studied with special attention to the selectivity for the formation of alcohols, where A-series=mainly Re-metal oxide catalysts, B-series=mainly Re-binary metal oxide mixture catalysts, and C-series=catalysts containing Fe.
Majority of the A-series catalysts exhibited measura ble activities with high selectivities for producing hydrocarbons. However there were several catalysts with better selectivities for producing alcohols. Results of activity tests on the B-series catalysts showed an outstanding effect of ZnO in raising the selectivity of methanol formation. A nitrogen-treated Re-Fe catalyst was prominent in the C-series catalysts, exhibiting a stable activity and a good selectivity for producing alcohols.
