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.
