Decomposition and Reduction of Nitrogen Oxide on Copper Loaded Mordenites

초록

동을 담지한 모더나이트를 이용하여 고정층 연속흐름 반응기에서 NO 분해와 CO에 의한 NO 환원을 실시하였다. NO 분해에서는 많은 동함랑에서 Cu°/HM이 CuO/HM보다 높은 분해 활성을 나타내었다. 이것은 Cu°/HM과 CuO/HM에 존재하는 Cu2+이온의 양과 CuO의 환원성 등의 차이에 관련된다고 보인다. NO 환원에서는 적은 동함량에서 Cuo/HM이 CuO/HM보다 높은 환원 활성을 나타내었다. 이것은 Cu°/HM과 CuO/HM에 존재하는 CuO의 환원성과 입자 크기 등의 차이에 관련된다고 보인다.

Catalytic decomposition and reduction of NO have been carried out on copper loaded mordenites in a packed bed flow reactor. For the decomposition of NO, Cu°/HM exhibited higher activities than CuO/HM at high copper content, which may be related to the difference in the amount of Cu2+ ions and the reducibility of CuO between Cu°/HM and Cuo/HM. However, Cu°/HM showed higher reduction activities than CuO/HM at low copper content. This result may be dependent on the difference in the amount of high-reducibility CuO between Cu°/HM and CuO/HM.
