Simultaneous Removal of NOx Uusing CuO/AC Catalyst at Low Temperature
CuO modified activated carbon(CuO/AC)was prepared by impregnation method under different conditions using coconut shell activated carbon as carrier.The denitrification performance of activated carbon before and after modification was investigated.The results show that CuO can greatly improve the denitrification performance of activated carbon.At the reaction temperature of 250 ℃(close to the flue gas window temperature),CuO/AC with a loading of 5％and a calcination temperature of 300 ℃ was used as a catalyst for simultaneous denitration,and the removal rate of NOx-was 94.31％.After continuous use for 44 h,the catalyst activity did not decrease.
