METHOD OF RECYCLING USED CAR TIRES Russian patent published in 2025 - IPC C08J11/14 B29B17/00 

FIELD: performing operations.

SUBSTANCE: invention relates to processing of used tires. Technical result is achieved by a method of processing used car tires, which includes their grinding, supply of the ground material to the reactor, its thermolysis in the reactor in the coolant medium with formation of gaseous and solid phases. Discharge of gaseous phase from reactor, its cooling and condensation. Separation of liquid phase condensed during cooling of gaseous phase. Removal of the solid phase from the reactor at the end of the thermolysis process, its cooling and unloading. Thermolysis process is carried out in a continuous mode. Tires are pre-crushed together with textile cord to particle size of not more than 6 mm with metal removal. Stay of crushed tires in reactor is 18-20 minutes, and the thermolysis process is carried out at temperature of 370-400 °C and pressure in reactor of 0.12-0.18 MPa. Crushed tires are loaded and unloaded without air oxygen access. Technical carbon obtained in the process of thermolysis as a solid phase is subjected to refining with recycled water with formation of water vapour and desorption of hydrocarbons from its surface.

EFFECT: simplification of the method of processing automobile tires, elimination of explosion hazard during implementation of the method and expansion of its technological capabilities.
