摘　　要：选择性催化还原(SCR)是火电厂烟气脱硝处理系统中的核心技术。为进一步提高脱硝效率和实现彻底净化,必须要加入TiO_(2)等催化剂。但是在脱硝过程中,烟气中存在的重金属、碱金属等,可能会导致催化剂失去活性。催化剂再生工艺能够使失活催化剂重新获得活性,从而降低了SCR脱硝系统的运行成本。Selective catalytic reduction(SCR)is the core technology of flue gas denitration treatment system in thermal power plants.In order to further improve the denitration efficiency and achieve complete purification,TiO_(2) and other catalysts must be added.However,in the denitration process,the presence of heavy metals and alkali metals in the flue gas may cause the catalyst to lose activity.The catalyst regeneration process can reactivate the deactivated catalyst,thus reducing the operation cost of SCR denitration system.
