车用三元催化转换器的研究进展及发展趋势

Progress in research of automotive three-way catalysts

对三元催化转换器的发展历程进行了综述,介绍了近些年三元催化转换器的研究进展,对转换器的催化剂进行了详细介绍,指出稀土催化剂的发展潜力。同时介绍了稀薄燃烧的催化转换器以及老化的转换器再生技术的研究进展,并对发展趋势进行了探讨。

The process of three-way catalysts is reviewed in this paper,in which the research progress of the catalytic converters in recent three years is introduced,and the catalyst of converter is introduced in details.The potential development of rare-earth catalyst is also pointed out.Simultaneously,the lean-burn catalytic converters and the research progress of regeneration of aged converter technologies are introduced.At last,its development trends are discussed further.
