废V2O5-WO3/TiO2催化剂中钛和钨元素的回收工艺研究进展

摘要

废V2O5-WO3/TiO2脱硝催化剂,若随意丢弃会使其中有效成分大量浪费并对环境造成污染,对其进行回收再利用是一个很好的解决途径.介绍了对废V2O5-WO3/TiO2脱硝催化剂中的钛、钨元素的回收工艺及原理,并对SCR脱硝催化剂回收工艺进行了展望.%Throwing away waste V2O5-WO3/TiO2 catalysts can cause significant waste of active ingredients and environment pollution, recycling and utilization of V2O5-WO3/TiO2catalysts are a good solution to this problem. In this paper, recovery technologies of Ti and W in V2O5-WO3/TiO2catalysts and their principles were introduced, and prospects of the recovery process of SCR DeNOx catalysts were pointed out.
