摘　　要：通过对国内外锰基吸附剂净化烟气中Hg^(0)研究成果进行了系统的总结,从活性物种、影响因素和反应途径等方面详细介绍了基于负载型锰氧化物的脱汞技术的研究进展,分析并讨论了载体材料对脱除Hg^(0)的影响规律和作用机制。提出了发展可回收利用、吸附氧化能力强、抗硫抗水性优、吸附脱汞成本低的锰基吸附剂是控制烟气汞排放的可行方向。This article systematically summarizes the research results of purifying Hg^(0) in flue gas by manganese-based adsorbents at home and abroad,introduces in detail the research progress of mercury removal method based on supported manganese oxide in terms of active species,influencing factors and reaction pathways.Meanwhile,the influence law and mechanism of the carrier material on the removal of Hg^(0) are analyzed and discussed.It is proposed that the development of manganese-based adsorbents that are recyclable,strong in adsorption and oxidation,excellent in sulfur and water resistance,and low adsorption cost of mercury is a feasible direction to control flue gas mercury emissions.
