Abstract:The research progress of low temperature denitrification of coke oven flue gas is introduced, including the mechanism, low temperature SCR denitration catalyst (noble metal catalyst, molecular sieve catalyst, carbon based material catalyst and metal oxide catalyst) and industrial application of coke oven flue gas low temperature denitration catalyst. In view of the poor resistance of low-temperature denitration catalyst to SO2 and water vapor, the solid acid catalyst was proposed, which could remove 98 % of NOx during 150~350 ℃. When the coke oven flue gas contained 1 000 ppm SO2 and 8 %vol water vapor, the denitrification rate would not decrease obviously in the first 20 hours.
