Abstract

Results of the investigation of decomposition of chlorofluorocarbon CFC-11 (CCI₃F) in atmospheric-pressure flowing nitrogen or air using a moderate-power (several hundred Watts) microwave torch plasma (MTP) are presented. The gas flow rate and microwave power (2,45 GHz) delivered to the discharge were 2÷4 l/min. and 400 W, respectively. Concentrations of the CFC-11 in the flowing nitrogen or air were 50%. The results showed that the CFC-11 decomposition efficiency using the MTP was 1O0%. The removal yield (several hundreds g/h) and energy yield (almost r kg/kWh) are superior to those obtained by means of other methods and make the tested MTP highly attractive for the practical destruction of chlorofluorocarbons.
