Abstract
A method of treating a fluorocarbon feedstock includes radio frequency induction heating of a zone of a reaction chamber to a temperature not exceeding 950° C. The feedstock heats up in the heating zone, and the reaction chamber pressure and heating zone temperature are chosen so that a fluorocarbon compound present in the feedstock dissociates or depolymerizes into a more desired fluorocarbon compound. A hot product gas, which includes the more desired fluorocarbon compound, is formed and then quenched to stabilize the more desired fluorocarbon compound.
