摘　　要：面对日益严苛的环保标准,火电厂高温烟气的脱硝技术相对成熟,钢铁行业的低温工业烟气脱硝技术仍有发展空间。针对低温工业烟气脱硝效率难满足环保标准的问题,本文从低温催化剂的组成、脱硝机理、低温催化剂的抗水抗硫性等方面梳理了低温工业烟气脱硝技术的研究进展。最终,总结了低温脱硝技术的限制因素与未来的发展方向,为低温脱硝技术的研究提供参考。In the face of increasingly stringent environmental standards,the denitrification technology for high-temperature flue gas in thermal power plants is relatively mature,but there is still room for development in low-temperature industrial flue gas denitrification technology in the steel industry.To address the problem that the denitrification efficiency of low-temperature industrial flue gas is difficult to meet environmental standards,this paper reviews the research progress of low-temperature industrial flue gas denitrification technology from the aspects of the composition of low-temperature catalysts,denitrification mechanism,and the water and sulfur resistance of low-temperature catalysts.Finally,the limiting factors and future development directions of low-temperature denitrification technology are summarized,providing reference for the research of low-temperature denitrification technology.
