Purge feeding means and method

Tire liquefying process reactor discharge system and method

A discharge system is used with a tire liquefaction process using a reactor. The system includes a receiver receiving unreacted components, including oil coated metal, from the reactor. The unreacted components are moved through a pyrolysis reactor where they are heated to a temperature sufficient to convert the unreacted hydrocarbon components to a liquid and to gas by way of pyrolysis. The liquid and the majority of gas are drawn off from the pyrolysis reactor. Discharge apparatus connected to the pyrolysis reactor converts the remaining gas to a condensate and discharges the metal. The condensate is also removed for further use.

The present invention includes a purge chamber which includes a chamber holding the interlocking solid material. An entrance port apparatus passes the interlocking solid material into the chamber where it is purged by a purging gas. An exit port apparatus passes the solid interlocking solid material from the chamber. Located within the chamber is other apparatus which move the interlocking solid material from the chamber through the exit port apparatus and other apparatus which prevent the binding of the interlocking solid material.

The reactor forms a chamber which contains the reaction process. There are accesses to the chamber for receiving shredded tires and oil. There are egresses from the chamber for discharging the tire oil and for discharging unreacted elements. Apparatus is located within the chamber which separates the unreacted components of the shredded tires from the tire oil. The apparatus also provides for the removal of the unreacted elements from the chamber means. The reactor also includes a heater which heats the inside of the chamber to a temperature sufficient to cause a reaction between the shredded tires and the oil.

Method and reactor for producing tire oil

Scrap rubber automobile tires, oil soluble plastics, as well as waste motor oil are disposed of by the process of the subject invention without polluting the nation's environment. Further, useful product synthesis gas, reducing gas, or fuel gas is produced. The rubber from the rubber tires and/or oil soluble plastics are dissolved in the waste motor oil to produce a homogeneous pumpable tire-oil which is separated from undissolved tire belt material containing undissolved rubber and/or oily material, solid residue, and off-gas comprising light hydrocarbons having a maximum atmospheric boiling point of 850.degree. F., and H.sub.2 S. The undissolved tire belt material is coked to produce off-gas, inorganic materials and carbon black. Off-gas form the liquefaction and coking reactors is cooled to produce organic condensate. The tire oil, carbon black, and condensate are mixed together and introduce into a partial oxidation gas generator for the production of synthesis gas, reducing gas, or fuel gas.
