dc.description.abstract | The impacts of O 2 , HCl, SO 2 , and NO existing in simulated coal-combustion flue gases on Hg 0 adsorption equilibrium and kinetics of sulfur-impregnated activated carbon were evaluated. The adsorption capacities increased when one acidic/oxidizing gas component coexisted with the baseline components, including CO 2 , H 2 O, and N 2 . The effectiveness of enhancing Hg 0 adsorption capacity for these components, in a declining order, was NO, HCl, O 2 , and SO 2 . When two acidic/oxidizing gas components were present in the baseline gases, especially when NO coexisted, sulfur-impregnated activated carbon had increasing Hg 0 adsorption capacities compared to that obtained at the baseline condition. In contrast, the presence of SO 2 with O 2 had deteriorating effects on Hg 0 adsorption. The reduction in Hg 0 adsorption capacity may be attributed to the formation of SO 3 known to compete for adsorption sites. When the flue gas contained at least three acidic/oxidizing components, the baseline/O 2 /HCl/NO gas resulted in the largest Hg 0 adsorption capacity. Full factorial analysis further suggested that NO possessed the greatest effects on enhancing the Hg 0 adsorption capacity in the simulated coal-combustion flue gases. Kinetic results also showed that sulfur-impregnated activated carbon with a larger equilibrium adsorption capacity under a given gas condition in general possessed poor adsorption kinetics. © 2012 Elsevier Ltd.
