Abstract

Results of investigation of decomposition of chlorofluorocarbons CCI₂F₂ (CFC-12) and CHClF₂ (CFC-22) conducted in air flowing under atmospheric-pressure using a coaxial-line-based microwave torch plasma are presented. Concentrations of the chlorofluorocarbons in the flowing air were up to 10%. The decomposition efficiency of both CCl₂F₂ and CHCIF₂ was almost 10O%. This implies that the coaxial-line-based microwave torch plasma can be a useful tool for decomposition of highly-concentrated chlorofluorocarbons in air at atmospheric pressure.
