The purpose of this study is to investigate the behavior of biomass gasification in the packed-bed, conducting gasification experiment and analysis of syn-gas in the reactor. In this study, pellets of black pine (ψ6.5mm×8.5mm) are fed intermittently with air as the gasification agent. The gasification experiments were carried out by two type gasification methods, such as updraft and downdraft setups. In the gasification tests, the temperature distribution in the gasification reactor and the gas compositions are measured and analyzed during gasification by thermo-couples inserted from a furnace wall and a micro gas chromatograph, respectively. Product gas before cooling were sampled for determine the amount of tar generation.
