The high-efficiency low-temperature denitration catalyst keeps the denitration efficiency above 90% when the flue gas temperature is 160 °C. Therefore, it is very suitable for the treatment of low-temperature flue gas and has a wide temperature window (150--300 °C). The traditional SCR denitration catalyst has a high activation temperature, and the optimal working temperature of the catalyst unit is 300-400 °C. The high-efficiency catalysts show good catalytic activity at relatively low temperature, and have broader application prospects compared with traditional catalysts.
　　
　　Foamed nickel plate/foamed iron-nickel plate can have the effect of uniform reaction. It is widely used in desulfurization and denitrification projects.
