- Application Filed: December 03, 2019
- Assignees: CHZ TECHNOLOGIES, LLC (Austintown, OH, US)
- Claim: 1. A Clean Fuel Gas source and a Char source, wherein a method for producing the Clean Fuel Gas source and the Char source comprises: inputting a carpet, rug, plastic, tire, manure, auto shredder residue, glass and carbon fiber composite material, municipal solid waste, medical waste, and/or waste wood waste source into a thermolysis system, wherein the thermolysis system comprises at least two reactors, at least two gas scrubbers, an oil/water separator, and an oil/tar cracker, wherein the reactors have a process temperature of about 300° C.-800° C. and generate tars and oils, and wherein all of the oils and tars are separated in the oil/water separator and the at least two gas scrubbers, thereafter cracked in the oil/tar cracker, and sent back to the secondary reactor; optionally increasing the moisture content of the waste source by injecting steam into the system or drying the waste source to decrease the moisture content; destroying and/or removing toxic compounds present in the waste source; and generating the Clean Fuel Gas source and the Char source, wherein the Clean Fuel Gas source and the Char source contain less than about 10 ppb of halogenated organic compounds.
- Claim: 2. The Clean Fuel Gas source and the Char source of claim 1 , wherein the Clean Fuel Gas source and the Char source generated are free of the halogenated organic compounds.
- Claim: 3. The Clean Fuel Gas source and the Char source of claim 1 , wherein the Clean Fuel Gas source and the Char source generated are free of tars and/or oils.
- Claim: 4. The Clean Fuel Gas source and the Char source of claim 1 , wherein the toxic compounds and the halogenated organic compounds comprise aromatics and polycyclic aromatic hydrocarbons, halogenated dibenzodioxins, halogenated dibenzofurans, biphenyls, pyrenes, cadmium, lead, antimony, arsenic, beryllium, chlorofluorocarbons, mercury, and nickel present in the waste source.
- Claim: 5. The Clean Fuel Gas source and the Char source of claim 1 , wherein the Char source comprises carbon and fillers, and wherein the Char source is suitable for further recycling or an additional step of removing fillers from the carbon for further reuse of the carbon and/or fillers.
- Claim: 6. The Clean Fuel Gas source and the Char source of claim 1 , wherein the method further comprises the separation of oil-soluble substances from a gas/vapor mixture following the thermolytic conversion of hydrocarbons in the waste source.
- Claim: 7. The Clean Fuel Gas source and the Char source of claim 1 , wherein the Clean Fuel Gas source is an energy source with from about 3,000 to 20,000 BTUs per pound of the waste source.
- Claim: 8. A Clean Fuel Gas source and a Char source, wherein a method for producing the Clean Fuel Gas source and the Char source comprises: shredding or grinding a carpet, rug, plastic, tire, manure, auto shredder residue, glass and carbon fiber composite material, municipal solid waste, medical waste, and/or waste wood waste source to provide a substantially uniform waste source into a thermolysis system providing indirect heat in a system that is free of oxygen, wherein the thermolysis system comprises at least two reactors, at least two gas scrubbers, an oil/water separator, and an oil/tar cracker, wherein all of the oils and tars are separated in the oil/water separator and the at least two gas scrubbers, thereafter cracked in the oil/tar cracker, and sent back to the secondary reactor, wherein at least one reactor has a process temperature of from about 300° C.−800° C. and a pressure range from about 10 to about 100 millibar; optionally increasing the moisture content of the waste source to about 5-20% by injecting steam into the system or by drying a waste source to have a moisture content of about 5-20%; destroying and/or removing toxic compounds present in the waste source; generating a Char source, wherein the Char source comprises carbon and fillers and is suitable for further recycling; and generating a Clean Fuel Gas source from the pyrolytic conversion of hydrocarbons in the waste source, wherein the Clean Fuel Gas source is free of toxic compounds and halogenated organic compounds, and wherein from about 3,000 to 20,000 BTUs per pound of the waste source is generated as the Clean Fuel Gas source.
- Claim: 9. The Clean Fuel Gas source and the Char source of claim 8 , wherein the toxic compounds and the halogenated organic compounds comprise aromatics and polycyclic aromatic hydrocarbons, halogenated dibenzodioxins, halogenated dibenzofurans, biphenyls, pyrenes, cadmium, lead, antimony, arsenic, beryllium, chlorofluorocarbons, mercury, and nickel present in the waste source.
