摘　　要：氨选择性催化还原(NH_(3)-SCR)脱硝是目前主流的烟气NO_(x)脱除技术。十二五期间,我国首次将氮氧化物减排列入环保约束性指标,国内一大批研究人员被此课题所吸引,发表研究论文数和研究水平都有了极大地提高,在降低催化剂活性窗口温度等方面取得了明显进展,占据近十年来国际学术界对该课题研究的主要地位。而这些研究中最有希望在超低温环境中应用的是Mn基SCR催化剂。对Mn基催化剂低温催化机理和改性体系进行论述。Selective catalytic reduction of NO_(x) by ammonia(NH_(3)-SCR)is main technology for NO_(x) removal.In the 12th Five Year Plan period,after China first included the NO_(x) emission amount into the national environmental index,a large number of researchers were attracted to the subject.The number of published research papers and research level have been greatly improved,and significant progress has been made in decreasing the work temperature window.Chinese researchers have taken over the main status in the worldwide range on this topic in the past decade.Among these studies,the most promising candidate catalyst system in ultra-low temperature conditions is the Mn based catalyst.In this paper,the low temperature catalytic mechanism and modification methods of Mn based catalyst were discussed comprehensively based on the literature inquiry.
