摘要：
A series of Ni-Mo/gamma-Al2O3 methanation catalysts containing La2O3 were prepared by impregnation. The activities of catalysts for CO and CO2 methanation were investigated. The surface properties of the catalysts were studied by TEM, XPS and chemisorption of CO. The experimental results show that the addition of La2O3 increases the activities for the methanation of CO and CO2, the dispersity of nickel on catalysts, the active nickel surface area and the concentration of nickel atoms on the surface of Ni-Mo/gamma-Al2O3 catalysts. At the same time, it also decreases the binding energy of Ni-2P3/2 in catalysts.
