摘　　要：指出了汞吸附剂脱汞技术是目前燃煤烟气专门脱汞技术,并概述了国内外燃煤烟气中脱汞吸附剂的研究现状。目前研发的汞吸附剂按载体类型可分为:碳基吸附剂、飞灰、矿物类吸附剂、金属类吸附剂、金属化合物类吸附剂和络合吸附剂。综合评述了不同种类吸附剂的脱汞效率、成本和适用条件等;尤其对吸附过程的影响因素进行了分析,阐明了汞的形态分布、吸附剂性质、烟气成分、温度和评价装置的影响,最后对该领域的研究方向做了展望。At present mercury sorbents technology is the special technology to remove mercury in coal-fired flue gas.The present research situation of mercury-removing sorbents used in coal-fired flue gas were summarized.The sorbents by carrier type could be divided into carbon-based sorbents,fly ash,mineral sorbents,metal sorbents,metal compound sorbents and complex sorbents. The mercury removal efficiencies,＇ costs, and application conditions of various sorbents were summarized. The influence factors of adsorption process were especially analyzed.The influences of form distribution, smoke components, nature of the sorbents, temperature and evaluation device were also illustrated. And finally, the future research directions in this field were suggested.
