In this study, we chose activated carbon modified by CoGl2 (20% loading) to remove the elemental mercury in flue gas. Particulate mercury accounted for 87% of total mercury, while elemental mercury accounted for 80.4% of gaseous mercury. Modified activated carbon adsorbed 97% of elemental mercury in gaseous mercury; however, the absorption liquid only absorbed 3% of elemental mercury. Consequently, modified acti- vated carbon was able to absorb gaseous mercury in coal combustion test efficiently. The results showed that the release ratio of Hg in coal was 59.5% , and 1 kg of modified activated carbon could absorb the gaseous elemental mercury in flue gas yielded by 208 t of coal. %R %U http://www.hjjkyyj.com/hjjkyyj/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
