Treatment Of CCl4 and CHCl3 emission in a gliding-arc plasma

Abstract

The decomposition of the chlorinated hydrocarbons CCl4 and CHCl3 in a gliding-are plasma was examined. The effects of initial concentrations, total gas flow rates and power consumption were investigated. The conversion of the hydrocarbons mentioned above was relatively high. It could reach 80% for CCl4 and 97% for CHCl3.. In atmospheric air as a carrier gas, the reaction was exothermic, and the main products were CO2, CO and Cl-2. The transformation into CCl4 was also detected for the decomposition reaction of CHCl3. The conversion of these compounds increased with increasing frequency of power supplied and decreasing total gas flow rate.
