Treatment of volatile organic compound by positive streamer corona using aseries gap

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