Abstract
The present invention provides methods for decomposing and extracting compositions for the recovery of petroleum-based materials from composites comprising those petroleum-based materials, comprising subjecting the compositions and/or composites to microwave radiation, wherein the microwave radiation is in the range of from about 4 GHz to about 18 GHz. The present invention also provides for products produced by the methods of the present invention and for apparatuses used to perform the methods of the present invention.
Claims27
A method for decomposing a composition comprising a petroleum-based material, comprising:
- subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition,
- wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz;
- and
- recovering decomposed petroleum-based material at a pressure less than one atmosphere, wherein said composition is derived from a tire.
A method for decomposing a composition comprising a petroleum-based material, comprising:
- subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition,
- wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz;
- and
- recovering decomposed petroleum-based material at a pressure less than one atmosphere, wherein said composition comprises plastic.
A method for decomposing a composition comprising a petroleum-based material, comprising:
- subjecting said composition to microwave radiation for a time sufficient to at least partially decompose said composition, wherein the temperature of said composition does not exceed about 700° F.;
- wherein said microwave radiation comprises at least one frequency component in the range of from about 4 GHz to about 18 GHz;
- and
- recovering decomposed petroleum-based material at a pressure less than one atmosphere.
