低碳烃选择性催化还原NO_x的研究进展

The advance in selective catalytic reduction of nitrogen oxides with hydrocarbons

对报道较多的以低碳烃作为还原剂,选择性催化还原NO的研究进展进行了综述,重点介绍了离子交换分子筛类催化剂、金属与金属氧化物的研究状况,分析了存在问题及今后的研究重点,简要介绍了固体超强酸类催化剂。

The advance in selective catalytic reaction of nitric oxide using hydrocarbons has been reviewed.The research status of ion-exchanged zeolites,metal and metal oxides was introduced emphatically.The existing problems and the work in the future were discussed.The ultra strength solid acids in SCR-HC were also described briefly.
