中文摘要: 氨选择性催化还原法(NH3-SCR)是目前最高效、最成熟的烟气脱硝技术。Mn基催化剂在选择性催化还原法(SCR)中展现出很高的低温活性,具有广阔的应用前景。但实际烟气中存在的H2O和SO2会引起Mn基催化剂的中毒失效,极大限制了其工业化应用。为了突破工业化应用瓶颈,分析了低温Mn基催化剂的H2O和SO2中毒机理,综述了其抗水抗硫研究进展。研究结论可为抗水抗硫低温Mn基催化剂的开发及应用提供理论基础。
Abstract:NH3-selective catalytic reduction (SCR) is the most efficient and mature flue gas deNOx technology at present.Mn-based catalysts show high low-temperature activities in SCR reaction and have broad application prospects.However,the presence of H2O and SO2 in flue gas could cause poisoning and deactivation of Mn-based catalysts,which greatly limits its industrial applications.In order to break through the bottleneck of industrial application,the H2O and SO2 poisoning mechanism of low-temperature Mn-based catalysts is analyzed,and the research progress of H2O and SO2 resistance is reviewed.The research conclusions provide a theoretical basis for the development and application of low-temperature Mn-based catalysts with H2O and SO2 resistance.
