柴油车尾气净化催化技术进展

Advances in catalytic technology for purification of diesel exhausts

介绍了柴油车尾气排放的特性及主要污染物,从颗粒物的催化再生技术、贫燃条件下NOx的选择性催化还原技术以及氧化催化技术等几个方面对柴油车尾气净化技术,尤其是催化技术进行了探讨,并提出了未来柴油车用催化剂的发展方向。

The characteristic of emissions and main pollutants from diesel emission were outlined. The technologies for purification of diesel engine exhausts were reviewed, especially catalytic regeneration of particulate matter (PM), selective catalytic reduction of NOx under lean combustion condition and catalytic oxidation. The trends of the purification catalysts for diesel vehicles were outlined.
