METHOD OF AND PLANT FOR THERMAL PROCESSING OF WORN-OUT TIRES Russian patent published in 2006 - IPC B29B17/00 F23G7/12 C08J11/16 B29K21/00 

FIELD: recycling or worn-out tires and other rubber articles.

SUBSTANCE: invention relates to thermal processing of hydrocarbon materials. According to proposed method of thermal processing of worn-out tires, finely divided tires are subjected to pyrolysis in reactor at temperature of 550-800°C in reducing gas produced in reducing gas generator by combustion of gases containing hydrocarbons, and products of pyrolysis are separated. Heat set is used in proposed method. At least part of gaseous products of pyrolysis getting out of reactor with vapors of liquid hydrocarbons is directed into reducing gas generator and heat set. At least part of flue gases getting out of heat set is directed to reducing gas generator and reactor. To implement the method, plant for thermal processing of worn-out tires is used containing reactor, system to let out gases forming in reactor, reducing gas generator connected to reactor, system to deliver finely divided worn-out tires into reactor, and receiver for insoluble residue of pyrolysis. Plant is furnished with heat set with flue gases outlet, and system to let gases forming in reactor is connected to reducing gas generator and heat set. Flue gases outlet device is connected to reducing gas generator and reactor.

EFFECT: dispensing with superheated steam which is replaced by flue gases, possibility of using products of pyrolysis instead of hydrocarbon gas at production of reducing gas.
