| 摘 要： | 在传统选择性催化还原技术（SCR）催化剂的基础上,分别以钒-钛系催化剂、固溶体催化剂和新型MnO x 催化剂为重点介绍了近些年低温SCR催化剂的研究进展,综述了不同活性组分的复合型催化剂的制备方法、元素掺杂、反应机理和抗性等,并通过分析不同复合型催化剂的表征总结了催化剂的性能状况以及低温脱硝效率,着重阐述了新型MnO x 催化剂所具有的优异脱硝特性,认为通过改性提高新型MnO x 的抗水抗硫性将会成为该领域未来的发展方向和研究热点,最后介绍了不同负载体对新型MnO x 催化剂的催化效率的影响规律,发现二氧化钛负载体具有良好的抗水性,三氧化二铝负载体能显著增强催化活性,二氧化铈负载体的热稳定性较好。

| Abstract: | On the basis of conventional selective catalytic reduction（SCR） catalysts,the research progress on low-temperature SCR catalysts was introduced by taking V-Ti catalysts,solid solution catalysts and new MnO x catalysts as key points.The preparation methods,element doping,reaction mechanism and resistance of composite catalysts with different active components were reviewed.By analyzing the characterization of different composite catalysts,the performance and low-temperature denitration efficiency of the catalyst were summarized.The excellent denitration characteristics of the new MnO x catalyst was emphatically expounded.It was considered that improving the water and sulfur resistance of new MnO x by modification would become the development direction and research hotspot in this field in the future.Finally,the influence of different carriers on the catalytic efficiency of the new MnO x catalyst was introduced.It was found that TiO2 carrier had good H2O resistance,Al2O3 carrier could significantly enhance the catalytic activity,and CeO2 carrier had good thermal stability. |
