摘要:Coal-fired flue gas has become a major source of mercury pollution. In this work, a novel active coke formula adsorbent(ACFA) was developed for Hg0 removal. All experiment were acted in simulated flue gas. Through experiment we found the Hg0 removal efficiency of the active coke formula adsorbent could reach up to 65.3 % and it was better than active FRNH¶VLQWKHZKROHDGVRUSWLRQSUR cess. Inferred the active coke formula adsorbent had CO and C=O functional groups by the FTIR chart of before and after adsorption. Comparing the XRD, it was deduced that the TiO2 crystals existed in the form of anatase in the adsorbent, which may be one of the reasons for the high activity of the adsorbent. Partial flue gas components affecting Hg0 removal efficiency (including O2, HCl, NO, SO2) had been studied. Results showed that O2 could effectively promote Hg0 removal, when the O2 content was 8%, the maximum removal efficiency was 70.8%; HCl and NO could effectively promote the Hg0 removal efficiency, which could reach up to 78% and 82% when added O2; SO2 itself was not conducive to Hg0 oxidation, the efficiency was improved after adding O2, but the effect was not very obvious.
