Abstract: 본 발명은 100 내지 650 ℃의 온도 및 0.5 내지 50바의 절대압에서 산소의 존재하에 탄화수소, 일산화탄소, 수소 또는 그들의 혼합물로 불균질 촉매상에서 배기 가스로부터 나온 NO x (x는 1 또는 2임)의 환원 방법을 개시한다.  불균질 촉매로서, 화학식 I A 1-x M 2 O 4 를 가지며 임의로 희토류 귀금속, 티타늄, 바나듐, 몰리브데늄, 텅스텐 또는 그들의 혼합물로 도핑된 이원 방식 또는 다원 방식 화합물이 사용된다.  화학식 I에서, A는 마그네슘, 칼슘, 티타늄, 바나듐, 크롬, 망간, 철, 코발트, 니켈, 구리, 아연, 주석 또는 그들의 혼합물을 나타내고, M은 알루미늄, 갈륨, 인듐, 주석, 크롬, 망간, 철, 코발트, 니켈, 구리, 아연 또는 그들의 혼합물을 나타내고, x는 0 내지 0.99이다.  상기 화합물 중의 산소 원자는 A가 사면체 위치에 위치하고, M은 팔면체 위치에 위치하며 등량의 M이 사면체 위치를 차지할 경우 A는 또한 팔면체 위치를 차지할 수 있는 가능한 조밀한 입방 구형 충전 방식으로 배열된다.
