Patent ID: 7375255

Claim:
A method of processing rubber tires each of which comprises a rubber casing and a metal wire embedded therein, comprising the steps of: (a) feeding said rubber tires into a reaction chamber having a deoxygenated environment, wherein each of said rubber tires is served in a whole piece manner without shredding said rubber tire in pieces into said reaction chamber one by one; (b) adding a catalyst into said reaction chamber to mix with said rubber tires; and (c) pyrolysing said rubber tires in said reaction chamber to vaporize said rubber tires such that said rubber casing of each of said rubber tires is decomposed into fuel oil, methane gas and carbon black to be collected as an energy source while said metal wire becomes residue for recycling use, wherein said step (c) comprises the steps of: (c.1) gradually increasing a temperature within said reaction chamber in said deoxygenated environment until said rubber casing of each of said rubber tires is vaporized to form vaporized gas and said carbon black without incinerating said rubber tire, wherein said metal wire becomes residue after said rubber casing is vaporized; (c.2) condensing said vaporized gas to extract said fuel oil therefrom while non-liquefied vapor gas becomes methane gas, wherein said vaporized gas is pumped out of said reaction chamber into a distillation facility for said vaporized gas condensing therewithin; and (c.3) individually collecting said fuel oil and said methane gas in said distillation facility, said carbon black in a vacuum apparatus that said carbon black is extracted out from said reaction chamber, and said residual metal wire to a steel collection bin for recycling use.
