Dependence of NOx Removal by Pulsed Streamer Discharge on the Input Energy Density to Nitric Oxide Ratio

Abstract Non-thermal plasma produced by pulsed power discharges in atmospheric pressure gases have been studied for the treatment of exhaust gases. In this paper, results are reported of short duration of tens of nanoseconds pulsed power applied to a mixture of nitric oxide (NO), nitrogen, oxygen, and water vapor, simulating flue gases to remove nitrogen oxide (NOx). The effects of the initial NO concentration and the pulsed repetition rate on the percentage of NO removal are reported. The results showed that all NO could be removed completely at different pulse repetition rates. NO removal ratio reached 100% at (3.2 ± 0.1) × 10
