バイオマスガス化改質へのメソポーラスシリカ触媒適用の基礎検討

抄録

Gasification is one of promising technologies for energy recovery from biomass including municipal solid waste. However, it has also problems such as reduction of tar and is required to increase the syngas yield. Then, we conducted experimental study on gasification and catalytic reforming of woody biomass using an electric tubular furnace to evaluate the performance of mesoporous silica catalyst supporting NiO. The results showed that the gaseous composition of H₂ significantly increased with catalytic reforming regardless of gasification agent. When only steam was used as gasification agent, H₂ generated was the highest and the concentration was 55 vol% in N₂ free condition, and the cold gas efficiency reached 77%. However, a clear result was not obtained about tar formation and decomposition by catalyst, and more research is needed.
