| Outline of Final Research Achievements |
A new plasma-catalytic gas reaction system with a spouted bed type plasma reactor was investigated, in which catalytic particles and plasma can efficiently contact with each other. It was found that the gas reaction behavior differs significantly depending on the particle packing volume, and that the reaction rate may be improved when the particles are well fluidized. It was also suggested that a stable micro-plasma may be formed by the particle filling and well-fluidization. We are assuming that the generation of this micro-plasma may contribute significantly to the improvement of the gas conversion rate.

地球温暖化の観点から，CO2を原料として有効に活用する技術開発が進められている．その一つに，CO2を原料とし，化学燃原料を合成するプロセスがあり，近年この合成にプラズマを利用した研究開発が活発に行われている．理論上，熱化学的合成手法に比べて高効率で合成可能であるが，現時点での反応率は低く，また工業用の装置も開発されていない．そのため，本研究で新たなプラズマガス合成装置として，噴流層型プラズマ装置を提案した．その結果，従来の固定層プラズマ装置に比べて新しく開発した噴流層のプラズマ装置は高効率でガス反応が促進可能であることが明らかになった．
