钒钛系SCR脱硝催化剂中毒及再生技术

Vanadium-titanium-based SCR denitration catalyst poisoning and regeneration technology

针对提高脱硝催化剂在火电厂脱硝装置中的循环综合利用效率,本文系统综述了现目前占燃煤电厂使用最多的钒钛系SCR脱硝催化剂中毒中主要元素碱金属元素(K、Na),碱土金属(Ca、As),P等中毒机理及再生技术.

In order to improve the comprehensive utilization efficiency of denitration catalyst in denitrifiqation equipment of thermal power plant,this paper systematically reviews the main elements such as alkali metal elements(K,Na),alkaline earth metals(Ca,As)and P etc.poisoning mechanisms and regeneration techniques in the vanadium-titanium SCR denitration catalyst which is currently used most in coalfired power plants.
