Improvement of efficiency of the use of pulsed corona discharge energy during the conversion of volatile organic compounds

Abstract

Abstract The effect of electronegative additives on the conversion of volatile organic compounds in plasma of air mixtures has been studied. It was shown that during the conversion of trichloroethylene C2HCl3 and perchloroethylene C2Cl4 in air under the action of pulsed corona discharge of nanosecond duration, the addition of carbon tetrachloride CCl4 to the mixture leads not only to a decrease in the discharge current, but also to an increase in energy efficiency of the conversion of toxic impurity. To explain the results obtained, the estimation of parameters of non-equilibrium non-thermal plasma and the analysis of processes in various regions of pulsed corona discharge have been carried out.
