디젤 미립자 물질의 직접 촉매 및 (반) 연속 산화를 위한 고 셀 밀도 또는 복잡한/난류 관류 모노리스 촉매 장치가 개시되어 있다. 촉매는 안정한 입방체 결정 구조를 갖는 OIC/OS 물질들에 관련하며, 특히, 촉진된 OIC/OS에 관련되고, 여기서, 촉진은 베이직(알칼리) 교환 프로세스를 통해 비-귀금속들의 합성후 도입에 의해 달성된다. 촉매는 추가로 귀족 그룹 금속들의 도입에 의해 촉진된다. There is disclosed high cell density or tortuous/turbulent flow through monolithic catalyst devices for the direct catalytic, and (semi) continuous oxidation of diesel particulate matter. The catalysts relate to OIC/OS materials having a stable cubic crystal structure, and most especially to promoted OIC/OS wherein the promotion is achieved by the post-synthetic introduction of non-precious metals via a basic (alkaline) exchange process. The catalyst may additionally be promoted by the introduction of Precious Group Metals.
