Abstract

The conventional methods of biomass gasification to hydrogen and synthesis gas have been carried out at high temperature. The purpose of this study is catalyst development for energy efficient power generation by catalytic gasification of biomass at lower reaction temperature. We have tested Rh/CeO2/SiO2 catalysts with various CeO2 content in cellulose gasification. We have found that the optimum content was 35wt% CeO2. From the comparison between our catalyst and conventional methods (steam reforming Ni catalyst, dolomite, noncatalyst) in terms of C-conversion to gas and cold gas effi-ciency, Rh/CeO2/SiO2 (35) catalyst exhibited much higher performance than other methods. It is suggest-ed that our catalyst can enhance the energy efficiency of power generation utilizing biomass gasification.
