摘　　要：以活性炭作为研究对象,采用经1%,5%,10%浓度的KCl和KBr溶液改性的活性炭进行烟气汞的吸附实验,结果表明,5%浓度的KBr溶液改性后的活性炭对烟气汞的吸附效果最好,穿透率为22.1%.选取了5%KCl改性后的活性炭进行了不同温度下的吸附实验,结果表明,在不同温度下,活性炭的吸附能力呈抛物线型,在120℃的条件下对烟气汞的吸附效果最好,穿透率为47.6%.In order to obtain an efficient sorbent to remove mercury in the flue gas at a coal-fired power plant,activated carbon is studied,which is modified by 1% ,5% and 10% KCl and KBr solu- tion. The results of the experimental data show that the activated carbon modified with 5% KBr or 5% KCl arrives at its highest adsorption efficiency and the penetration rate is 22.1% and 47.6% re- spectively. And activated carbon modified with 5% KCl is selected to test at different temperatures, and the result of the test demonstrates that activated carbon modified with 5% KC1 is up to its best adsorption efficiency and the penetration rate is 47.6% under the temperature of 120 ℃.
