Abstract

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