A new microwave catalytic reactor system was developed. By coupling the catalytic effect of microwave irradiation with the reducing activity of activated carbon, the microwave catalytic reduction of nitric oxide (NO) was studied in activated carbon bed. Novel results were observed under microwave irradiation. 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 exhaust gas temperature under microwave irradiation was much lower compar...
