Online NO_X Removal from Stationary Diesel Engine Exhaust by Barrier Discharge Plasma

摘要

This paper reports plasma treatment of a 5 HP stationary diesel engine exhaust at full flow-rate (approximately 387 l/min) energized by power frequency AC. Glass and Chlorinated Polyvinyl Chloride (CPVC) tubes were used as the dielectric barriers. Significant removal of NO and NO_X has been achieved with barrier discharge plasma. The reactors were specially fabricated to facilitate high flow and high temperature associated with the engine exhaust. Studies were aimed at online cleansing of oxides of nitrogen from the exhaust without using any conventional catalysts/adsorbents. The results were discussed in detail for the cases studied.
