凹凸棒石烟气脱汞吸附剂的研究进展
Research progress in attapulgite absorbents for mercury removal from flue gases
摘要
Abstract
Injection is one of the effective ways to remove elemental mercury (Hg0) from coal-fired flue gas,and the key is the absorbent.Due to its many advantages of unique structure,superior performance,low cost,easy availability,and environmental friendliness etc.,attapulgite (ATP) is commonly used as absorbent.What's more,appropriately modified attapulgite exhibits excellent mercury removal performance,which endows it good prospects for industrial application.In this paper,adsorption characteristics of attapulgite and its application progress in Hg0 removal from flue gases were presented.Mercury removal performances of natural ATP and modified ATP,together with modifiers and the modification methods were summarized,then the mercury removal mechanism of such absorbents was analyzed.Meanwhile,the effects of flue gas components,adsorption temperature and amount of absorbent on mercury removal efficiency were discussed.Finally,we pointed out that further research should focus on the development of organic-inorganic composite modified absorbents with outstanding performance and good stability.Meanwhile,the mercury removal mechanism should be further studied in order to realize its industrial application.关键词
