中文摘要：选择性催化还原(SCR)法是目前世界上应用较为成熟的烟气脱硝技术之一,由于传统的适用催化剂的起活温度偏高,因此开发低温高效、性能稳定的催化剂已成为该技术成功运用的关键。分析了SCR法的脱硝原理,对目前广泛研究的低温SCR催化剂的分类及其运用进行了综述,提出了研究中尚需解决的问题,最后展望了未来的研究方向。

外文摘要：Selective catalytic reduction as one of a mature technology for denitration of flue gas has widely applied in the world.However,most of traditional catalyst exhibit their catalytic activity only at high temperature,so exploration of novel catalysts which have high catalytic activity and efficiency at low temperature become the key factors in selective catalytic reduction.In this paper,the mechanism of denitration in selective catalytic reduction is analyzed;the classification and application of widely researched low temperature SCR catalyst was summarized;finally,the problems in need of further discussion and study are advanced.
