Abstract

A dielectric barrier discharge powered by pulsed power supply system was used for the decomposition of tetrachloromethane, trichloromethane and trichloroethylene. The study was performed in atmospheric air with concentration of water vapor 0.4%. The effect of specific energy on overall halocarbons conversion and selectivity of halocarbons conversion to carbon dioxide, carbon monooxide, chlorine and hydrogen chloride was studied. In studied system the increase of the specific energy increased the selectivity of halocarbons conversion to carbon dioxide and chlorine. For the specific energy ~7 kJ/mol, the maximum conversions of tetrachloromethane, trichloromethane and trichlorothylene were 66, 60 and 93% respectively.
