In the present work, the methanation of carbon deposited on an alumina-supported nickel methanation catalyst was studied using temperature programming techniques. Two forms of surface carbon were identified, an ..cap alpha..-state with high and a ..beta..-state with low reactivity towards hydrogen. The objectives of this work were to determine the nature of the surface carbon, the kinetics of reaction with hydrogen, and the rate of deactivation of the active ..cap alpha.. state.
