Abstract

본 발명은 망간광석을 이용한 질소산화물의 제거방법에 관한 것으로, 좀 더 상세하게는 배기가스중의 질소산화물을 선택적 촉매 환원법으로 제거하는 방법에 있어서, 천연망간광석을 촉매로 사용하여 질소산화물을 제거 하는 방법에 관한 것이다. 상기 촉매는 150~300℃의 저온에서 질소산화물을 완전하게 제거할 수 있을 뿐만 아니라 미반응된 암모니아의 방출로 인하여 발생될 수 있는 부작용을 배제할 수 있는 효과가 있다.The present invention relates to a method for removing nitrogen oxides using manganese ore, and more particularly, in the method for removing nitrogen oxides in exhaust gas by selective catalytic reduction, using natural manganese ore as a catalyst to remove nitrogen oxides. It is about how to. The catalyst not only completely removes nitrogen oxides at a low temperature of 150 to 300 ° C., but also has an effect of excluding side effects that may occur due to the release of unreacted ammonia.
