제목 MeClx-loaded V2O5/TiO2-based catalysts for simultaneous removal of mercury and NO in SCR process
초록 The MeClx-loaded V2O5/TiO2-based SCR catalysts were examined to investigate the role of metal chloride in SCR process for simultaneous removal of NO and mercury. The activity for mercury oxidation significantly increased by loading MeClx to V2O5/TiO2-based catalyst, especially under SCR condition. The MeClx -loaded TiO2-based catalysts revealed high activity for mercury oxidation even in the absence of HCl. This may indicate the Cl in MeClx act as chlorine source to oxidize elemental mercury to oxidized mercury(HgCl2). However, The activity of MeClx -loaded catalysts for NO removal greatly decreased with the increase of temperature above300~ 350oC, which may be due to the oxidation ability of MeClx for NH3 oxidation in SCR reaction. The MeClx-loaded V2O5/TiO2 catalysts can be promising SCR catalyst for mercury oxidation. However, the effect of MeClx on NO removal should be closely examined for simultaneous removal of NO and mercury in SCR process.
