Conversion of a Waste Refrigerant Mixture containing CFC-12, HCFC-22 and HFC-134a to Non-Crosslinked Fluoropolymer in a Non-Thermal Plasma

2 Discipline of Chemistry, School of Environmental and Life Sciences, The University of Newcastle, Callaghan, NSW 2308, Australia Abstract: The reaction of a waste refrigerant mixture of CFC-12, HCFC-22 and HFC-134a (in an argon/methane bath gas) in a dielectric barrier discharge non-thermal plasma reactor has been studied. The conversion of the major refrigerant, CFC-12, ranged from 59–76 % for an input energy density range of 3–13 kJ/L. The reaction results in the formation of a range of gaseous products as well as non-crosslinked polymers of two distinct fractions.
