Abstract：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.
