Gliding discharge plasma in a large scale reactor was used for decomposition of tetrachloromethane. The new power supply system based on a power inverter was used. The conversion of CCl4 was investigated in air at normal pressure. The reactor was made of a quartz-glass tube 60 mm in diameter and contained three converging electrodes 140 mm long. Effects of the initial CCl4 concentration, gas flow rate and discharge power on CCl4 conversion have been studied. The conversion of CCl4 was high in all cases reaching a maximum of 90%. The conversion of tetrachloromethane decreased with increasing initial concentration of CCl4 in the reaction mixture. Changing the gas flow rate from 1000 Nl h-1 to 1400 Nl h-1 decreased the conversion of tetrachloromethane.
