Deactivation and regeneration of SCR catalysts have caught wide attention.Based on a comprehensive literature review,deactivation mechanisms of traditional SCR catalysts by catalyst sintering,arsenic,calcium,alkali and so on were discussed.Based on the research on various deactivation mechanisms,the optimal design of SCR denitration system and measures of preventing catalyst deactivation can be performed according to the boiler characteristics,fuel characteristics,and fly ash components.It is of great significance for expanding catalyst lifetime and reducing the operation and maintenance cost of the system.
