| 摘要 |
Systems and methods for processing pyrolyzable materials in order to recover one or more usable end products are provided. Pyrolysis methods and systems according to various aspects of the present invention are able to thermally decompose carbon-containing materials, including, for example, tires and other rubber-containing materials, in order recover hydrocarbon-containing products including synthesis gas, pyrolysis oil, and carbon black. Systems and methods according to aspects of the present invention may be successful on a commercial scale, and may be suitable for processing a variety of feedstocks, including, but not limited to, used tires and other types of industrial, agricultural, and consumer waste materials. |

1. A method for pyrolizing a rubber-containing material in a commercial-scale pyrolysis facility, said method comprising:
(a) at least partially filling at least a first, a second, a third, and a fourth crucible with respective first, second, third, and fourth quantities of rubber-containing material; (b) loading each of said first, second, third, and fourth crucibles into a respective first, second, third, and fourth individual heating zone, wherein the individual heating zones are collectively defined within one or more pyrolysis furnaces; (c) heating each of said first, second, third, and fourth crucibles within said respective first, second, third, and fourth individual zones under conditions sufficient to pyrolyze at least a portion of said first, second, third, and fourth quantities of rubber-containing material to thereby form pyrolysis vapors and pyrolysis solids in each of said first, second, third, and fourth crucibles, wherein said pyrolysis solids include metallic elements; (d) recovering a pyrolysis gas and/or a pyrolysis liquid from at least a portion of said pyrolysis vapors withdrawn from said first, second, third, and fourth crucibles in at least one separation zone; (e) cooling at least a portion of said pyrolysis solids in said first, second, third, and fourth crucibles; and (f) separating at least a portion of the cooled pyrolysis solids in a solids processing zone to thereby provide separated metallic elements and carbon black, wherein said facility has an average daily production rate, measured over a 30-day period, of at least 15 tons per day. |
