Claims
- 1. A method for the production of carbon and water comprising contacting an organic material with at least one of carbon dioxide, carbon monoxide and combinations thereof at a temperature between about 200° C. and about 600° C.
- 2. The method of claim 1, wherein the organic material is selected from the group consisting of polymers, elastomers, cellulosics, agricultural wastes and solid fuels.
- 3. The method of claim 1, wherein the temperature is between 300° C. and about 500° C.
- 4. The method of claim 1, wherein the temperature is between 350° C. and about 450° C.
- 5. The method of claim 1, wherein the organic material is shredded or cut to a size of less than about 2 inches in the longest dimension.
- 6. The method of claim 1, wherein the organic material is selected from the group consisting of rubber, insulated communication wire, polyethylene, polyvinyl chloride, wood, sawdust and coal.
- 7. The method of claim 1, wherein the contacting is conducted in a stainless steel rotary kiln.
- 8. The method of claim 1, wherein the contacting is conducted at a pressure greater than atmospheric pressure.
- 9. The method of claim 1, wherein the carbon dioxide is supplied as a compound selected from the group consisting of sodium carbonate, potassium carbonate, ammonium carbonate, bicarbonate, magnesium carbonate, zinc carbonate and combinations thereof.
- 10. The method of claim 1, wherein the carbon monoxide is supplied as a compound selected from the group consisting of sodium formate, potassium formate, magnesium formate and zinc formate.
- 11. The method of claim 1, wherein the at least one of carbon dioxide, carbon monoxide and combinations thereof is supplied as a mixture with water vapor at a temperature greater than about 300° C.
- 12. The method of claim 1, wherein the contacting step is performed in the presence of ceric sulphate.
- 13. The method of claim 1, comprising the additional step of burning hydrocarbon gases created in the contacting step to create heat for maintenance of the temperature of the contacting step.
- 14. The method of claim 1, wherein the contacting step is performed in the presence of air.
- 15. A method for the production of carbon and water comprising:
a. contacting an organic material with a compound selected from the group consisting of carbon dioxide, carbon monoxide and combinations thereof at a temperature between about 200° C. and about 600° C., b. capturing vapors created in the contacting step, and c. recycling the captured vapors to the contacting step.
- 16. The method of claim 15, wherein the compound is selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium formate, potassium formate, magnesium formate, zinc formate and combinations thereof.
- 17. The method of claim 15, wherein the organic material is selected from the group consisting of rubber, insulated communication wire, polyethylene, polyvinyl chloride, wood, sawdust and coal.
- 18. A method for the production of carbon and water comprising:
a. contacting an organic material with at least one of carbon dioxide, carbon monoxide and combinations thereof at a temperature between about 200° C. and about 600° C., b. scrubbing any oils and waxes produced in the contacting step with a compound selected from the group consisting of hydroxides, carbonates and bicarbonates to form a soap-like material, and c. recycling the soap-like material to the contacting step.
- 19. The method of claim 18, wherein the organic material is selected from the group consisting of rubber, insulated communication wire, polyethylene, polyvinyl chloride, wood, sawdust and coal.
- 20. The method of claim 18, wherein the compound is magnesium carbonate or zinc carbonate.
- 21. The method of claim 18, wherein the compound is selected from the group consisting of sodium hydroxide, potassium hydroxide, sodium carbonate, sodium bicarbonate, sodium formate, potassium formate, magnesium formate, zinc formate and combinations thereof.
