Hot syngas cleaning of biomass gasification using molten carbonate is suggested for high temperature fuel cell (MCFC, SOFC). The molten carbonate is absorbent of desulfurization and dechlorination, and catalyst of tar cracking. Thus, this gas cleaning system consists of a few stages which are molten carbonate reactor and particulate filter. The operating temperature of molten carbonate reactor is 700-1000℃, and is kept by the heat of gasification gas, etc. In this study, the removal of H_2S and the decomposition of tar using molten carbonate were performed in the bench scale test stand. The performances of gas cleaning were confirmed by using the molten carbonate fuel cell.
