摘　　要：Ni-based catalysts supported on di erent supports （α-Al2O3,γ-Al2O3, SiO2, TiO2, and ZrO2） were prepared by impregnation. Effects of supports on catalytic performance were tested using hydrodeoxygenation reaction （HDO） of anisole as model reaction. Ni/α-Al2O3 was found to be the highest active catalyst for HDO of anisole. Under the optimal conditions, the anisole conversion is 93.25% and the hydrocarbon yield is 90.47%. Catalyst characteriza-tion using H2-TPD method demonstrates that Ni/α-Al2O3 catalyst possesses more amount of active metal Ni than those of other investigated catalysts, which can enhance the cat-alytic activity for hydrogenation. Furthermore, it is found that the Ni/α-Al2O3 catalyst has excellent repeatability, and the carbon deposited on the surface of catalyst is negligible.
