Gas-phase Hg⁰ Removal by a Fe₂O₃/AC Catalyst

Abstract:

Gas-phase elemental mercury (Hg⁰) removal by an activated coke (AC) supported Fe₂O₃ catalyst (Fe₂O₃/AC) was studied under N₂+HCl atmosphere and compared with that by AC. The influences of Fe₂O₃ loading, temperature and inlet Hg⁰ concentration on Hg⁰ removal were investigated. The results indicate that the Hg⁰ removal capability of Fe₂O₃/AC was much higher than that of AC, indicating the important role of Fe₂O₃ oxidation activity. The capability of Fe₂O₃/AC increased with an increase of Fe₂O₃ loading (1-10 wt.%) and temperature (120-200 °C). Scanning electron microscope-energy dispersive X-ray (SEM-EDX) analysis confirmed the correlation between Fe₂O₃ and Hg adsorbed over Fe₂O₃/AC.
