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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
