    Abstract
  • Targeting the oxidation of elemental mercury (Hg 0) in the flue gas from coal-fired power plant, the research progress of the catalytic oxidation by modified selected catalytic reduction (SCR) catalysts for elemental mercury was reviewed, focusing on the influence of metal oxides or chlorides doped SCR catalysts on elemental mercury oxidation. The activity of modified SCR catalysts for elemental mercury was explored from the effects of dopant, doping ratio, flue gas components and temperature. In addition, the heterogeneous reaction mechanisms between elemental mercury and the modified SCR catalysts were analyzed synthetically with respects to doping elements and flue gas conditions. Finally, considering the current situation of coal-fired plants, the prospects of future studies on modified SCR catalyst and the relevant experimental methods were proposed.
