Isobutanol and Methanol Synthesis on Copper Catalysts Supportedon Modified Magnesium Oxide

Abstract

Alcohols are selectively produced from CO/H2 on K–CuMgCeOx catalysts, but synthesis rates are strongly inhibited by CO2 formed during reaction. Reaction pathways involve methanol synthesis on Cu, chain growth to C2+ alcohols, and metal–base bifunctional coupling of alcohols to form isobutanol. Ethanol reactions on K–Cu0.5Mg5CeOx show that Cu catalyzes both… (More)
