摘　　要：总结了燃煤烟气中汞污染控制的技术原理、技术特点、研究现状及进展情况,对比了烟气中较难脱除的单质汞(HgO)污染控制技术的优缺点,概述了烟气中单质汞脱除方法,展望了蛭石黏土类矿物对燃煤烟气中汞的吸附脱除方面的应用潜力,提出了对燃煤烟气中单质汞吸附净化的研究思路。In this paper, the principle, technological characteristic, present condition and the progress of mercury from flue - gas combustion were summarized. The research methods and technical development about Hg removal were also introduced, advantage and disadvantage of the technical for removing single quality mercury （Hg^o） were compared, which was the most difficult component to be removed from fuel gas. Then the prospect of mercury（Hg^o）adsorbed on clay such as vermiculite was put forward. This may become a new method for mercury pollution control of coal combustion gas.
