选择性催化还原技术(SCR)在水泥行业脱硝中被广泛应用，其中，高温范围内（280–350 ℃）已有较为完善的SCR技术及体系，但在中温区仍有待突破。本工作以中温脱硝催化剂为重点，综述了Mn、Ce、V系脱硝催化剂的研究进展，并分析了Sm、Nb、Ho、Sb、La、Mo、Pr的掺杂对于脱硝催化剂的改性，结合水泥窑炉烟尘中SO2、H2O、碱金属含量高的特点，分析了脱硝催化剂中毒原因，对催化剂的抗H2O、SO2、碱金属中毒性能进行了探讨，展望了水泥行业SCR中温脱硝催化剂的研究前景。

Selective catalytic reduction (SCR) technology has been widely used in the denitrification of cement industry, in which a relatively mature system has been formed in the high temperature (280–350 ℃) section, but there is still a breakthrough in the middle temperature zone. Focusing on medium temperature catalysts, this paper reviewed the progress of Mn, Ce and V catalysts, and analyzed the doping of Sm, Nb, Ho, Sb, La, Mo and Pr to improve the performance of catalysts. Combined with the characteristics of the high content of SO2, H2O and alkali metal in cement kiln smoke, the causes of catalyst poisoning were analyzed, and the way to resist sulfur poisoning, water poisoning, and alkali metal poisoning was summarized. The research prospect of SCR medium temperature denitration catalyst in cement industry is prospected.
