摘　　要：随着国内外对燃煤电厂汞污染的重视,大力开发和推广一种经济、有效的控汞技术具有重要意义。活性炭作为一种常见的高效吸附剂,也已在烟气脱汞中有了大量的研究。本文通过阅读大量的文献,针对目前国内外活性炭除汞的现状,介绍了活性炭脱汞效率的影响因素,归纳了活性炭对汞的吸附类型。通过对目前控汞技术的深入了解,发现改善烟气环境和改性活性炭都能较好地提升汞的脱除率。As coal-fired power plants in domestic and overseas pay attention to the mercury pollution, it has important significance to develope and promote an economic and effective technology for the mercury control. As a common efficient adsorbent, activated carbon has been studied in removing mercury from the flue gas. With refer- ence to a lot of literature, the influence factors of activated carbon by the mercury-removal are introduced in view of the present situation of activated-carbon applications, and the adsorption types of the activated carbon for the mer- cury removal summarized. Based on present understanding of the mercury-control technology, it is showed that im- proved flue gas environment and modified activated carbon could enhance the mercury removal rate.
