摘　　要：现有脱汞技术存在成本高、对设备有腐蚀的问题,通过对传统SCR催化剂进行改性,提高汞氧化性能,开发出同时脱硝脱汞新型催化剂,考察了NH3以及HCl等对脱汞性能的影响。结果表明:SCR催化剂改性后零价汞氧化率可达40%以上,NH3对零价汞的催化氧化有抑制作用;HCl对零价汞的催化氧化基本无影响。The existing problem of mercury removal technology was high cost and corrosion of equipment. Modification of traditional SCR catalyst can greatly improve Hg0 oxidation performance,so a new catalyst having denitration and De-Hg was developed. It was studied the effects of NH3 and HCl on the mercury removal performance. The result shows that removal efficiency of mercury can reach 40% after Modification of SCR catalyst. NH3 inhibits oxidation efficiency of elemental mercury; but HCl has almost no influence.
