Two series of Ni Mo/γ Al 2O 3 Methanation Catalysts were prepared by impregnation and coprecipitation,and characterized by TPR.Methanation activity and sulfur resistance of catalysts were examined. The effects of the promoter of Mo and rare earth on the activity,sulfur resistance and surface structure were investigated .It shows that promoter Mo play an important role on the methanation activity, sulfur resistance and selectivity.The catalyst promoted by 10% of Mo has the fastest reduction speed in TPR...
