Filed:

Apr 27, 1993

Appl. No.:

8/053727

Inventors:

Craig J. Castagnoli - Rowland Heights CA
Hong P. Wang - Diamond Bar CA

Assignee:

Texaco Inc. - White Plains NY

International Classification:

C07C 100

US Classification:

585241

Abstract:

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.

International Classification:

C10B 104
C10B 4714
C10B 5300

US Classification:

201 3

Abstract:

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.

International Classification:

C10B 4718
C10B 5300

US Classification:

201 3

Abstract:

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.

International Classification:

F23K 300

US Classification:

34182

Abstract:

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.

International Classification:

F23K 300
C10B 4718

US Classification:

201 3

Abstract:

A purge chamber for purging oxygen from interlocking, solid material, such as shredded tire pieces, prior to further processing of the material in a liquefaction apparatus. The purge chamber includes a chamber for holding interlocking, solid material An entrance port is connected to the chamber for passing the interlocking, solid material into the chamber. A purge device communicates with the chamber for providing a purging gas to the chamber. An exit port of the chamber passes the interlocking, solid material from the chamber. An auger screw mounted in the chamber, when rotated, moves the interlocking, solid material from within the chamber into the exit port.
