Experimental Study on Removing NO from Flue Gas Using Microwave Irradiation over Activated Carbon

Abstract

The microwave catalytic reduction of NO was studied in activated carbon bed. The conversion of NO to N2 under microwave irradiation remarkably increased compared to conventional heating, which indicates that the microwave irradiation has microwave catalysis effect besides thermal effect. The effects of a series of reaction parameters on the productivity of N2 with a new microwave catalytic reactor system were investigated. The results show that NO is converted predominantly to N2 under all reaction conditions and the highest conversion of NO to N2 is up to 99.8% under optimized conditions.
