过渡金属基分子筛是在氨选择性催化还原氮氧化物技术领域广泛应用的一类催化材料,在实际应用中容易中毒失活。失活形式主要有水热老化失活,P、S中毒失活,HCs中毒失活及尿素中毒失活等。本文分析了过渡金属基分子筛催化剂的4种失活机制及相应的抗失活工艺,并展望了过渡金属基分子筛的发展方向。

Transitional metal based zeolites are widely used to remove nitrogen oxides by NH3 -SCR, which will eventually become de-activated in practical application proceses, including hydrothermal aging, P and S poisoning, HCs poisoning and urea poisoning. The deactivation mechanisms and the related methods to improve the resistance to deactivation are reviewed. The development trends of the transitional metal based zeolite are outlined.
