摘要
Synergistic effects of pulsed DC dielectric barrier discharge （DBD） plasma and Indium modified HZSM-5 （In/HZSM-5） catalyst for C2H2 selective reduction of NOx at 200℃, in the presence of enriched oxygen by using a one-stage plasma-over-catalyst （POC） reactor, are reported. With a reactant gas mixture of 480 ppm NO, 500 ppm C2H2, 13.0% O2 in N2 and gas hourly space velocity （GHSV） = 10000 h^-1, pure catalytic, pure plasma-induced （discharges over fused silica pellets） and plasma-catalytic NOx conversion percentages are 45.0%, 4.0% and 92.2%, respectively. NOx conversion rates and energy costs were also compared for pulsed DC DBD and AC DBD reactors.
