摘要
在Y型分子筛及其负载金属和离子交换催化剂上，考察了低温下SO2对NO催化氧化的影响，发现在分子筛催化剂上SO2对NO氧化同样具有低温活性促进作用，同时也造成了催化剂的失活。本文借实验结果和参考文献，对SO2在分子筛上的活性促进和失活机理提出了初步看法。
Abstract : Effect of S02 on catalytic oxidation of NO at low temperature over zeolite Y and its supported metal and ion - exchanged catalyst is studied. It is showed that S02 has a promoting effect for NO oxidation over zeo-lites at low temperature and meantimes causes gradual deactivated of catalyst. The effect of S02 on catalytic ox-idation over zeolite Y and the deactivation mechanism are investigated through experiments results and some references.
