Promoting effect of the interaction between Ni and CeO2 on steam gasification of biomass

Abstract Catalytic performance of Ni/CeO 2 /Al 2 O 3 catalysts prepared by a co-impregnation method was higher than that of Ni/CeO 2 /Al 2 O 3 by a sequential impregnation method and Ni/Al 2 O 3 in steam gasification of biomass in terms of the yield of coke and tar. Characterization by means of temperature programmed reduction suggests that the intimate interaction between Ni and CeO 2 on the Ni/CeO 2 /Al 2 O 3 by the co-impregnation method can be related to high performance in steam gasification of biomass.
