Abstract

The hydrogenation reactivity of surface carbon deposited by CO decomposition was investigated for a rhodium-vanadium catalyst. It appeared that the rate of methanation of reactive surface carbon is decreased by vanadium. The reactivity towards C2+ hydrocarbons is enhanced by vanadium. The relation between stronger adsorbed carbon atoms and the formation of higher hydrocarbons is discussed. ASED calculations support the proposal that changes in metal-carbon bond strength have a significantly larger effect on the rate of methanation than on carbon chain growth.
