Gas-phase elemental mercury (Hg0) removal by activated coke (AC) supported metal oxide catalysts MxOy/AC (MxOy=MnO2, Fe2O3, CuO) were studied under N2+HCl atmosphere and compared with that by AC. The influences of MxOy loading, temperature and Hg0 concentration on Hg0 removal were investigated. The results indicate that the capabilities of MxOy/AC for Hg0 removal were much higher than that of AC, indicating the important role of MxOy. The capabilities were found to follow the trend MnO2/AC > Fe2O3/AC > CuO/AC, which was corresponding to the oxidation activities of MxOy. The Hg0 removal capability of MnO2/AC increased with an increase of the MnO2 loading (1-10 wt.%) and temperature (120-200 °C). Scanning electron microscope-energy dispersive X-ray analysis confirmed the correlation between MnO2 and Hg adsorbed over MnO2/AC.
