一种恢复火电厂钒钛基SCR脱硝催化剂活性的活化再生剂
摘要：
本发明公开了一种恢复火电厂钒钛基SCR脱硝催化剂活性的活化再生剂，包括活化再生剂A和活化再生剂B，活化再生剂A和活化再生剂B分别包括以下重量比例的组分：活化再生剂A包括四丁基氟化铵、柠檬酸、氨基磺酸、烷基酚聚氧乙烯醚，其余为去离子水溶剂；活化再生剂B包括正钒酸铵、仲钨酸铵，其余为去离子水溶剂；上述化学药剂均为优级纯，去离子水为二级除盐水或以上级别的纯水。本发明应用于火力发电厂中，用于对SCR脱销系统的催化剂进行活化再生处理，能够大大提高SCR脱硝催化剂的活性，不仅降低了脱硝成本，还减少了废弃催化剂填埋所产生的环境二次污染，具有重要的经济效益。
摘要（英）：

The invention discloses an activating regeneration agent for restoring the activity of a vanadium-titanium-based selective catalytic reduction (SCR) denitration catalyst in a thermal power plant. Theactivating regeneration agent for restoring the activity of the vanadium-titanium-based SCR denitration catalyst in the thermal power plant is prepared from an activating regeneration agent A and an activating regeneration agent B. The activating regeneration agent A is prepared from the following components in percentage by weight: tetrabutylammonium fluoride, citric acid, sulfamic acid, alkylphenol ethoxylates and the balance of a deionized water solvent; and the activating regeneration agent B is prepared from the following components in percentage by weight: ammonium vanadate, ammonium paratungstate and the balance of a deionized water solvent. All the chemical agents are guarantee reagents, and deionized water is second-grade demineralized water or above. The activating regeneration agent is applied to the thermal power plant to activate and regenerate the catalyst of the SCR denitration system, the activity of the SCR denitration catalyst is can greatly improved, the denitrationcost is reduced, the secondary environment pollution generated by the waste catalyst landfill is reduced, and important economic benefits are achieved.
