Pyrolysis and gasification technology is one of the energy conversion methods using biomass. The fuel gas is obtained by pyrolysis and gasification reactions, but condensable organic compounds so-called tar is also generated. Tar clogs the pipe of gasifier and break turbine, therefore must be reduced. In a fluidized bed gasifier, contact frequency between tar and ash is high, thus, tar reduction effect by ash contained in the biomass is expected. In this study, we have conducted an experiment thermal decomposition of cellulose by constructing an experimental device that assumes the heterogeneous reaction in a fluidized bed gasifier. K_2CO_3 and Ca(OH)_2 that are compound of K and Ca contained in the biomass ash were selected as the catalysts. The amount of condensable products and heavy tar were decreased, also the amount of gaseous products were increased by installing K_2CO_3 and Ca(OH)_2 In heterogeneous reaction between tar and ash, K_2CO_3 and Ca(OH)_2 have the catalytic effect to decompose the tar, to enhance gaseous production.
