Hydrodeoxygenation of Anisole over Ni/α-Al2O3 Catalyst

Ni-based catalysts supported on different supports ( α -Al 2 O 3 , γ -Al 2 O 3 , SiO 2 , TiO 2 , and ZrO 2 ) were prepared by impregnation. Effects of supports on catalytic performance were tested using hydrodeoxygenation reaction (HDO) of anisole as model reaction. Ni/ α -Al 2 O 3 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 characterization using H 2 -TPD method demonstrates that Ni/ α -Al 2 O 3 catalyst possesses more amount of active metal Ni than those of other investigated catalysts, which can enhance the catalytic activity for hydrogenation. Furthermore, it is found that the Ni/ α -Al 2 O 3 catalyst has excellent repeatability, and the carbon deposited on the surface of catalyst is negligible.
