Thermal gasification and reforming technologies applicable over a wide temperature range were investigated for high efficiency and calorific value of gas from organic waste such as woody debris. Using laboratory-scale catalytic reformers and gasifier, durability of reforming catalyst and availability of catalyst regeneration were discussed. Commercial Ni-based catalyst and calcined limestone (CaO) were applied to the reforming reaction. From the results of woody waste gasification and reforming, produced hydrogen concentration was sustained at a high catalyst temperature of 1123 K, which prevented the catalyst from deactivating. Moreover, the results indicate that catalyst regeneration by air oxidation at the same temperature would be effective for enhancing the catalytic activity.
