Abstract
The present invention relates to a method of recycling polymeric waste products into monomers and high value forms of carbon by pyrolytic conversion using an induction coupled RF plasma heated reactor.
Claims3
A method of recycling polymeric materials into monomers and high value forms of carbon comprising:
- (a) injecting a powder of polymeric materials comprising polyethylene, polypropylene, polystyrene, polyethylene terepthalate, or polyvinyl chloride into an induction coupled RF plasma heated reactor so that the polymeric materials of the powder are pyrolytically converted to monomers and high value forms of carbons;
- and
- (b) isolating the monomers and high values forms of carbon from the reactor.
