| Abstract: | In the selective catalytic reduction (SCR) flue gas denitration system, alkali ,alkaline earth metal poisoning and regeneration of catalysts have aroused widespread concern. This paper describes and compares the research progress of alkali metal poisoning mechanism of the SCR denitration catalysts and research thought based on the molecular level. According to the mechanism of catalyst deactivation, the methods designed to improve the resistance to alkali metal and regeneration methods of poisoning catalyst are reviewed. |
