摘要
概述了燃煤烟气中汞的吸附特性,综述了活性炭、飞灰和其它吸附剂对汞的吸附机理和影响因素,探讨了汞的吸附模型。指出活性炭对汞的脱除效率可达到90%以上,但成本高,飞灰吸附成本虽然低但脱除效率有限,其它吸附剂研究尚处于初级阶段,因此寻找廉价高效的吸附剂十分必要,同时开发烟气中污染物的联合脱除技术是研究方向。
Mercury and its adsorption characterization in flue gas were summarized in detail as a result of adsorption affection factors and mechanism by active carbon,fly ash and other sorbents,as well as mercuric adsorption model.It concluded that active carbon has 90% removal efficiencies but with expensive cost,while fly ash has low cost but finite efficiencies,other sorbent research is under research.It is very necessary to search high effective and cheap sorbents so as to develop integrative pollutants removal technologies.
