Abstract
본 발명은 배가스에 함유된 질소산화물을 암모니아를 환원제로 사용하여 물과 질소로 분해시켜 제거하는 경우 사용되는 철이온 교환된 모더나이트계 제올라이트 촉매에 관한 것으로, 본 발명에 의하여 규소와 알루미늄의 중량비(Si/Al)가 4내지 6이며, 철이온으로 최대 100% 이온교환된 질소산화를 제거용 모더나이트계 제올라이트 촉매가 제공된다. 상기 촉매는 질소산화물 제거활성 및 SO2에 대한 내구성이 우수하며 SO2에 대한 산화력이 낮은 것이다.The present invention relates to an iron ion-exchanged mordenite zeolite catalyst which is used when the nitrogen oxide contained in the flue gas is decomposed into water and nitrogen by using ammonia as a reducing agent. Si / Al) is 4 to 6, there is provided a mordenite-based zeolite catalyst for removing nitrogen oxidation up to 100% ion exchange with iron ions. The catalyst has excellent durability for removing NOx activity and SO 2, and to lower the oxidizing power of the SO 2.
