    摘要: A method of treating a fluorocarbon feedstock includes generating, in a high temperature zone, an electrical arc between at least one cathode and at least one anode, generating in the high temperature zone and by means of the electrical arc and a plasma gas, an upwardly burning thermal plasma having a tail flame, allowing a solid particulate fluorocarbon feedstock comprising at least on fluorocarbon compound to form a reactive thermal mixture with the thermal plasma tail flame, with the fluorocarbon compound dissociating into at least one fluorocarbon precursor or reactive species, and cooling the reactive thermal mixture to form, from the fluorocarbon precursor of reactive species, at least one more desirable fluorocarbon compound.
