Abstract: Decomposition of chlorinated hydrocarbons, CCl_4 and CHCl_3, in gliding plasma was examined. The effects of initial concentrations, total gas flow rates, and power consumption have been investigated. The conversion result was relatively high. It reached 80% for CCl_4 and 97% for CHCl_3. Using atmospheric air as the carrier gas, the plasma reaction occurred at exothermic reaction and the main products were CO_2, CO, and Cl_2. Transformation into CCl<FORMULA>_4 was also detected for CHCl_3 decomposition reaction. The conversion of CCl_4 and CHCl_3 were increased with the increasing applied frequency and decreasing total gas flow rate.
