Current Status and Progress of Research on Denitrification Technology for Low-temperature Industrial Flue Gas
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.
