Treatment of Volatile Organic Compound by Positive Streamer Corona Using a Series Gap

Abstract
The nonthermal atmospheric pressure plasma produced by streamer corona discharge was used for the treatment of volatile organic compounds (VOCs). The decomposition rate of toluene as a VOC was investigated under various discharge conditions of discharge period, pulse rise time of discharge voltage and gas flow rate. The quantity of byproducts due to the toluene decomposition was controlled by the discharge parameter, that is, pulse rise time of discharge voltage applied between discharge electrodes.
