英文摘要: The promoting effect of La2O3 on Ni/gamma-Al2O3 methanation catalyst was investigated by XPS, TPR and TPD methods. Results indicated. that La2O3 can be partially reduced to LaOx (x < 3/2) during H-2 reduction of the Ni catalysts with La2O3. The excess charge associated with the LaOx earl be transfered to Ni. It weakened C-O bond strength, accelerated CO dissociation, proportionation and methanation reaction.
