Abstract

A novel catalytic process for biomass gasification at 773-873 K with high energy efficiency was developed. A cellulose was used as the model compound of biomass, and the performance of the catalysts was compared with that of dolomite and non-catalysts in batch- and continuous-feeding fluidized bed reactor. In reaction tests with various catalysts, Rh/CeO2 had a higher performance than other catalysts, but also showed deactivation during the reaction which was attributed to the sintering of the CeO2 support. A commercial steam-reforming catalyst also displayed high activity, but was deactivated due to carbon deposition. Rh/CeO2/SiO2 gave higher C-conversion to gas and was more stable than Rh/CeO2. The gasification using the Rh/CeO2/SiO2 catalyst produced a higher yield of synthesis gas at much lower temperature and with higher stability.
