Low Temperature DeNOx Catalyst for Selective Catalytic Reduction and Preparation Method Thereof

The present invention relates to a low temperature denitrification catalyst for selective catalytic reduction reaction and a method for manufacturing the same. More particularly, the present invention relates to: the low temperature denitrification catalyst for selective catalytic reduction reaction which is excellent in removing nitrogen oxides in exhaust gas even at low operating temperatures and a treated gas does not cause secondary environmental pollution, and also has a strong poisoning resistance so that nitrogen oxide removal efficiency is not reduced even after long-term operation, at the same time can contribute to practical use by using a commercial vanadium-based catalyst instead of manganese-based catalyst; and the method for manufacturing the same. 본 발명은 선택적 촉매환원반응용 저온 탈질촉매 및 그 제조방법에 관한 것으로, 보다 상세하게는 낮은 운전온도에서도 배기가스 중의 질소산화물 제거효율이 우수하고, 처리된 가스가 2차 환경오염을 유발하지 않으며, 강한 피독저항성을 가짐에 따라 장기간 운전하여도 질소산화물 제거효율이 저하되지 않는 동시에 망간계 촉매가 아닌 상용 바나듐계 촉매를 사용하여 실용화에 기여할 수 있는 선택적 촉매환원반응용 저온 탈질촉매 및 그 제조방법에 관한 것이다.
