Removal of mercury vapor in simulated coal derived flue and fuel gases over activated carbon and iron oxide adsorbents in a temperature range of 80-150℃ using a flow-type packed-bed reactor was studied. Both activated carbon and iron oxide captured elemental mercury vapor in the simulated flue gas in the absence of H_2S. The Hg removal activity was accelerated by the presence of H_2S. The activated carbon was more active than the iron oxide at 100℃ for the simulated flue gas in the presence of H_2S. The iron oxide was more active than that of the activated carbon for Hg removal from the simulated fuel gas.
