摘　　要：废旧SCR(Selective Catalytic Reduction)催化剂是燃煤、冶炼、水泥等行业生产过程烟气脱销工段中产生的固体废弃物,对废旧SCR催化剂进行安全处置也成为了当前亟需解决的问题。本文介绍了废旧SCR催化剂的失活原因,和水洗、酸洗、热处理等再生技术,以及不能再生SCR催化剂中有价金属钛、钨、钒的分离和回收技术,推动废旧SCR催化剂再生和有价金属回收工艺的进一步研究。Spent SCR(Selective Catalytic Reduction)catalysts are solid waste generated in the flue gas desulfurization in industries such as fire coal,smelt and cement,which has become an urgent issue to be solved.It summarized the deactivation reasons of SCR catalysts and the regeneration technologies including water or acid washing and heat treatment,as well as the separation and recovery technologies for valuable metals such as titanium,tungsten,vanadium in nonrenewable SCR catalysts.
