In this study, the removal of elemental mercury (Hg0) by KI and KBr modified activated carbons (KI-ACs and KBr-ACs) was studied under simulated flue gas conditions. The physicochemical properties of these catalysts were investigated by a variety of characterization methods. The effects of KI and KBr loading, adsorption temperatures and the flue gas components on Hg0 removal efficiency were investigated. The results showed that the Hg0 removal efficiency for the ACs was significantly enhanced by KI or KBr modification, and the KI-ACs performed much better than the KBr-ACs in terms of Hg0 removal under the same conditions. An increase in KI or KBr loading and adsorption temperatures improved the Hg0 removal efficiency, which indicated that chemisorption occurred. |
