Abstract

In this study, Catalytic reforming with vapor and biomass gasification was simultaneously performed in a same fixed bed reactor at $600-800^{\circ}C$. Light gases were produced from reformation of the tar (fuel gases) in biomass gasification by using limonite and dolomite, as catalysts. Hydrogen and carbon dioxide are main components in light gases. Hydrogen yields increased with temperature increasing in the range of $650-800^{\circ}C$, because the water shift reaction was promoted by catalyst. The yield of hydrogen gas was increased about 160% under catalyst with the mixture of limonite and dolomite comparing to limonite only.
