The Research of SCR Catalyst for Elemental Mercury Conversion in Coal-Fired Flue Gas

To control mercury pollution has become a major issue nowadays. The SCR systems in power plant can oxide the elemental mercury into oxidized mercury, which can be removed by WFGD, it became a very feasible measures to control mercury pollution. The core part of SCR system is SCR catalyst. The influence of different metal composition and modification of SCR catalyst and the gas composition in simulative flue gas for the efficiency of the conversion of elemental mercury are introduced ,for sifting the catalyst with high efficiency for mercury conversion under the condition of low temperature.
