O211 電気加熱式ドロップチューブ反応炉によるCO_2および水蒸気を用いた木質バイオマスの基礎ガス化特性(セッション4:技術～基礎～,口頭発表)

抄録

Fundamental gasification characteristics in CO_2 and H_2O atmospheres at high temperature are experimentally studied, using an electric heated drop tube furnace. The gasification experiments are performed, changing temperature at the furnace wall, gasification agents and residence time. Hinoki sawdust is selected as a fuel. In the experiments, the gas composition and the elemental compositions in the residual reaction particles are analyzed. The result shows that co-existence of CO_2 with H_2O can enhance the gasification performance, compared with the individual gasification characteristics.
