燃煤电厂汞污染越来越受到关注，目前具有应用前景的脱汞方法为吸附脱汞，因此研发高效低成本的脱汞吸附剂被广泛研究。在搭建的固定床吸附反应系统上对自制的褐煤活性焦脱汞性能进行了实验研究，研究了汞污染物的入口浓度，吸附剂的量、烟气成分及吸附剂的种类对吸附汞的影响。结果表明：活性焦吸附剂对烟气中的气态汞均有一定的吸附能力，其吸附效果随着入口汞浓度和吸附剂量的增加而增加；烟气中的SO2、NO气体对活性焦吸附汞有一定的促进作用。活性焦脱汞效率与载硫活性炭、脱汞专用活性炭相比还存在一定差距，但可通过改进活性焦的活化方式提高脱汞性能。

Coal-fired power plant mercury pollution has attracted a growing concern, now the current mercury removal method which has an application prospect is the adsorption of mercury removal, and therefore the development of cost-effective mercury removal sorbent been studied extensively. An experiment was conducted to study the effects of lignite activated coke on the mercury adsorption using a bench-scale fixed bed,including the inlet concentration of mercury pollutants,the quality of adsorbent,the composition of flue gas and the type of adsorbent and so on.The results show that the lignite activated coke has some adsorption capacity for mercury in flue gas,the activated coke adsorption rate increases with the increase of entrance mercury concentration and the quality of activated coke.The SO2,NO in flue gas can improve mercury adsorption capacity of activated coke.Although the mercury adsorption capacity of activated coke is lower than activated carbon with S solution and activated carbon only for mercury adsorption,the improvement of activation way of activated coke can enhance the performance of its mercury adsorption.
