摘要
随着全球交通系统的发展 ,特别是贫燃发动机的设计和应用 ,汽车尾气中排放大量的NOX 不仅严重地影响了环境 ,而且威胁到人类的身心健康 ,对净化汽车尾气中NOX 的催化剂的研究成了国际上研究热点。本文综合了烃类选择性还原催化剂的研究状况以及它们的优缺点 ,分析各类催化剂的前景 。
With the development of global traffic system,especially,the design and application of engines in lean-burn condition, a great deal of NO X from automotive exhaust not only affect badly on the environment ,but also threat the health of human So the research of de-NO X catalysis for automotive exhaust control has become a popular subject The research state,the advantages and disadvantages of catalysts using HC to reduce nitrogen oxides kinds of catalysts,and prospect about new-type-carrier catalysts are discussed
