SO2对Y型分子筛选择性催化氧化NO的影响
Effect of SO2 on Selective Catalytic Oxidation of NO over Y Zeolite
【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】 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.
