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

Catalytic performance of Ni/CeO2/Al2O3 catalysts prepared by a co-impregnation method was higher than that of Ni/CeO2/Al2O3 by a sequential impregnation method and Ni/Al2O3 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 CeO2 on the Ni/CeO2/Al2O3 by the co-impregnation method can be related to high performance in steam gasification of biomass.
