| 摘 要： | 催化剂是选择性催化还原(selective catalytic reduction,SCR)脱硝技术的核心,催化剂的低温活性、选择性和稳定性直接影响到NOx的脱除效果.SCR脱硝催化剂性能主要取决于催化剂活性组分和催化剂载体.简述了以氨、尿素和碳氢化合物等不同物质作为SCR还原剂的化学反应原理;介绍了以贵金属(Pt,Pd,Rh,Au等)和金属氧化物(V2O5,WO3,FeaO3,CuO,CrOx,MnO2.MoO3和NiO等)为催化剂活性组分.以分子筛、柱撑黏土、碳基材料和TiO2等为催化剂载体的SCR脱硝催化剂的研究进展.以V2O3为主要活性组分,以TiO2为载体的钒钛类催化剂因其理想的综合性能,目前已商业化应用.纳米有序结构TiO2薄膜可望成为理想的SCR脱硝催化荆新型载体. |

| Abstract: | The catalyst is a key to the selective catalytic reduction(SCR) technique to remove NOx from effluent gas.The activity,selectivity and stability of SCR catalysts directly determine the NOx removal efficiency.The properties of SCR catalysts are influ-enced by the active component and the substrate of SCR catalysts.In this paper,the reactions of SCR with different reducers such as ammonia,urea and hydrocarbon are generalized.The research progress in the SCR catalyst field using the noble metals(Pt,Pd,Rh,Au,et... |
