| Outline of Final Research Achievements |
The aim was to improve the performance of the zero-emission filter, which simultaneously achieves recovery of sulfur oxides and purification of nitrogen oxides in engine exhaust gas. Further improvement of reactivity in the low-temperature high-space-velocity region is an issue for miniaturization and high performance. In order to increase the reaction activity in the low temperature range, we established a method of synthesizing a new metal oxide by combining cerium with manganese oxide, and succeeded in activating the purification performance of this material in the low temperature range. A manganese oxide filter without base material was prepared to maintain reaction activity under high space velocity. We have obtained a filter design guideline that can maintain reaction activity even under high space velocity conditions.

本研究は，ディーゼルエンジンの排ガスのゼロエミッション化と硫黄回収による硫黄循環社会構築を目指している。希薄燃焼の排ガスの特徴である酸化雰囲気中でのゼロエミッション化を可能とするゼロエミッションフィルターは，全海域上の大気環境の保全につながる社会的意義を有する．また，近年再生可能エネルギーから生成されたカーボンフリー燃料であるアンモニアを燃焼させた排ガス浄化にも課題として挙げられる微量の硫黄酸化物を浄化の可能性を見出した点が学術的意義として大きい点である．
