Nickel-based catalyst is known to be active on biomass tar reforming. However, nickel-based catalyst was found to be deactivated by coke fouling on the catalyst surface. Calcined dolomite is a low price natural mineral. It was found to be effective on coking resistance during tar steam reforming. In this study, light fuel gases were produced from biomass tar gasification using calcined dolomite and nickel-based catalyst. Catalytic gasification was performed in a fixed bed reactor at 650℃. Calcined dolomite was filled over nickel-based catalyst. As a result, coke deposits decreased compared to the case with nickel catalyst only.
