A low energy method of pyrolysis of rubber or other hydrocarbon material is provided. The hydrocarbon material is heated while maintaining a vacuum, using a clay catalyst. In an additional embodiment, the temperature of the reaction chamber and corresponding fuel input is varied either over time or spatially within the reaction chamber, to take advantage of the exothermic properties of the reaction. With the method of the present invention, a higher quality solid reaction product can be achieved, as well as a liquid having reduced polyaromatic hydrocarbons and oxidized organic contaminants.

1. A low energy method of pyrolysis of hydrocarbon material comprising:providing said hydrocarbon material;loading said hydrocarbon material into a reaction chamber;adding a clay catalyst and an elemental metal dust catalyst to said reaction chamber, andheating said reaction chamber for a sufficient tune to provide substantially complete pyrolysis,said method occurring while maintaining a vacuum in said reaction chamber and yielding reaction products comprising a substantially non-charred and non-oxidized carbon black having minimal unpyrolyzed material, a substantially non-oxidized and polyaromatic hydrocarbon-free liquid hydrocarbon product and a combustible gas. 2. The method of claim 1, wherein said clay is selected from the group consisting of montmorillonite, bentonite, beidillite and combinations thereof. 3. The method of claim 1, wherein said clay is pillared clay. 4. The method of claim 1, wherein said clay is a natural ore. 5. The method of claim 1, wherein said clay is a commercial clay containing product. 6. The method of claim 5, wherein said commercial clay product is selected from the group consisting of cat litter and oil spill absorbent and combinations thereof. 7. The method of claim 1, wherein said clay and metal dust catalyst is added in an amount of about 0.01 wt. % to 3.0 wt. %, based on the total weight of said hydrocarbon material. 8. The method of claim 1, wherein the metal dust is added to the clay in a ratio of between about [0.1 to 2]:[0.1 to 2]:[8] of [Al] [Mg] [clay]. 9. The method of claim 1, wherein said metal dust is added in a ratio of between about [0.5 to 1]:[0.5 to 1]:[8] of [Al] [Mg] [clay]. 10. The method of claim 1, wherein said metal dust is comprised of a mixture of aluminum and magnesium. 11. The method of claim 1, wherein said metal dust is comprised of aluminum or magnesium. 12. The method of claim 1, wherein said metal dust comprises Al particles of less than about 200 mesh size and Mg particles of less than about 325 mesh size. 13. The method of claim 1, wherein said heating of said reaction chamber results in a reaction temperature of said hydrocarbon material of between about 150° to 850° F. 14. The method of claim 13, wherein said reaction temperature of said hydrocarbon material is maintained for a period of time sufficient to complete pyrolysis. 15. The method of claim 1, wherein said heating occurs in at least a first, second and third phases and fuel input is adjusted to take advantage of the exothermic nature of the reaction. 16. The method of claim 15, wherein said heating in said first phase maintains a reaction temperature of between about 450°-850° F., for a period of time adequate to initiate pyrolysis. 17. The method of claim 15, wherein said heating in said second phase maintains a reaction temperature of between about 450°-850° F., for a period of time adequate to provide continued pyrolysis. 18. The method of claim 15, wherein said heating in said third phase maintains a reaction temperature of between about 450°-850° F., for a period of time adequate to provide completion of pyrolysis. 19. The method of claim 15, wherein said first, second and third phase occur sequentially over time. 20. The method of claim 15, wherein said first, second and third phase occur sequentially over space, as said hydrocarbon material moves through said reaction chamber. 21. The method of claim 1, wherein said vacuum is maintained at a pressure of between about 2 inches to 16 inches mercury. 22. The method of claim 15, wherein said vacuum is maintained at pressure of between about 2 inches to 16 inches mercury. 23. The method of claim 1, wherein said vacuum is maintained at a pressure of between about 5 inches to 10 inches mercury. 24. The method of claim 15, wherein said vacuum is maintained at pressure of between about 5 inches to 10 inches mercury. 25. The method of claim 1, wherein said hydrocarbon material is used rubber. 26. The method of claim 1, wherein said hydrocarbon material is tar sands. 27. The method of claim 1, wherein said hydrocarbon material is coal.
