摘要: 催化剂作为选择性催化还原(selective catalytic reduction, SCR)烟气脱硝系统的重要核心部分，催化剂的消耗对于脱硝系统的运行成本有着重大影响。为此，主要介绍了回收废弃脱硝催化剂的回收方法，包括固化处理法和化学处理法。其中着重介绍了化学处理中酸浸法、碱浸法以及焙烧法，分析总结了3种工艺各自的特点。并对未来关于废催化剂的处理实现工业化提出了相应的意见。
Abstract: As an important part of the selective catalytic reduction (SCR) flue gas denitration system, the catalyst consumption has a great influence on the operating cost of the denitration system. For this reason, the recovery methods for the recovery of waste denitration catalysts are mainly introduced, including the curing and chemical treatment methods. Among them, the acid leaching method, alkali immersion method and roasting method in chemical treatment were introduced. The characteristics of the three processes were analyzed and summarized. We put forward corresponding opinions about the waste catalyst treatment to achieve industrialization in the future.
