Abstract
A method of treating a fluorocarbon feedstock includes heating, by means of radio frequency induction, a heating zone to a high temperature, allowing a fluorocarbon feedstock, comprising at least one fluorocarbon compound, to heat up in the heating zone so that the fluorocarbon compound dissociates into at least one fluorocarbon precursor or reactive species, and cooling the fluorocarbon precursor or reactive species, thereby forming, from the fluorocarbon precursor or reactive species, at least one more desired fluorocarbon compound.
Claims18
A method of treating a fluorocarbon feedstock, which method includes
- heating, by means of radio frequency induction, a heating zone of a reaction chamber to a temperature not exceeding 950° C.;
- allowing a fluorocarbon feedstock, comprising at least one fluorocarbon compound, to heat up in the heating zone;
- choosing a reaction chamber pressure and a heating zone temperature so that the fluorocarbon compound dissociates or depolymerizes into at least one more desired fluorocarbon compound;
- forming a hot product gas comprising the more desired fluorocarbon compound;
- and
- quenching the hot product gas to stabilize the more desired fluorocarbon compound.
A quench probe which comprises
- an outer cylindrical component providing a central passageway and adapted to cool a hot gas passing through the passageway;
- a plurality of circumferentially spaced elongate teeth or scrapers protruding inwardly from the outer component into the passageway;
- an inner cylindrical component located with clearance inside the outer component, with the inner component adapted to cool the hot gas passing along the peripheral gap between the components;
- a plurality of circumferentially spaced elongate teeth or scrapers-protruding outwardly from the inner component into the passageway, with these teeth or scrapers being staggered with respect to the teeth or scrapers on the outer component;
- and
- drive means for driving the one component to oscillate relative to the other component.
A novel method of treating a fluorocarbon feedstock, substantially as described and exemplified herein.
A novel quench probe, substantially as described and illustrated herein.
