The catalytic gasification of cellulose to synthesis gas has been studied under mild conditions in a laboratory scale batch-feeding and fluidized bed reactor using air as a gasifying agent and Ar as a cellulose carrier from the feeder to catalyst bed under atmospheric pressure. Various types of support materials and supported metal catalysts have been investigated in this process. The flow conditions were 60 and 50 cm3 (STP)/min of air and Ar, 2 cm height of the fluidized bed and 0.7 s residence time of volatiles. From this investigation CeO2 has been found as the best support and Rh/CeO2 has been found as an excellent catalyst in the cellulose gasification at 823 K, which resulted in 100% C-conversion to gas. The use of Rh/CeO2 catalyst in the secondary bed resulted in lower yield of CO and H2.
