METHOD OF PROCESSING POLYMER COMPONENTS OF WORN-OUT CAR TYRES Russian patent published in 2010 - IPC C10G1/10 C08J11/04 

FIELD: chemistry.

SUBSTANCE: invention relates to method for thermal processing polymer components of worn-out car tyres, involving their loading into a reactor, pyrolysis in a gas medium with subsequent separation of pyrolysis products and unloading the solid residue. Crushed polymer components of worn-out car tyres are treated with an aqueous solution of cobalt chloride in amount of cobalt chloride of 2% of the weight of polymer components and subsequent drying of the treated material at room temperature. Pyrolysis is carried out in a nitrogen medium at atmospheric pressure at 450-460°C for 1.0-1.5 hours.

EFFECT: invention increases output of gaseous and liquid pyrolysis products, and increases heating capacity of the gaseous products.
