Sulfur poisoning is one of the critical degradation mechanisms for ammonia selective catalytic reduction (SCR) catalysts and it is therefore essential to examine the sulfur poisoning and regeneration. This is, to our knowledge, the first kinetic model presented, for sulfur poisoning and regeneration of Cu-zeolites used for NH₃-SCR.
