Research on Technology of Coal-fired Boiler Flue Gases Mercury-removing by Activated Carbon

针对近年来的燃煤烟气汞污染控制技术的发展现状,文章综述了活性炭吸附脱汞技术的最新研究进展,介绍了活性炭吸附、改性活性炭吸附及活性炭纤维吸附脱汞技术,指出了活性炭脱汞技术存在的问题及活性炭的脱附再生,从降低成本,减少二次污染,多种方法联合应用及污染物一体化控制等方面指出了活性炭脱汞技术的未来研究方向。

According to the development of the mercury pollution control technologies for coal-fired flue gases,the updated methods of mercury removal by carbon-based sorbents technology were summarized. The studies of mercury removal by activated carbon or chemically treated carbons or activated carbon fiber were highlighted in the paper. Based on the problems of mercury removal by carbon-based technology and activated carbon desorption and rege ner- ation,the author pointed out the development direction of mercury removal by carbon-based technology from the aspects of reducing cost, reducing re-pollution, mixed methods application, multi-pollutant control, and so on.
