Abstract: A method of processing of shredded rubber-containing waste involves its preliminary preparation, thermal decomposition in a furnace, separation of decomposition products into vapor-gas mixture and solid residue, and separation of a heavy hydrocarbon fraction from the vapor-gas mixture. Preliminary preparation of the waste is carried out by its blowing with water vapor until a waste temperature reaches 100° C., and thermal decomposition is carried out in residual oil in the starting phase, and afterwards in the atomized generated heavy hydrocarbon fraction and superheated water vapor, their weight ratio being (0.1-0.5):1. The heavy hydrocarbon fraction is separated from the vapor-gas mixture with water by atomizing it into the vapor-gas mixture flow at the rate of 5-15% of the mass flow rate of the mixture, while metal is extracted from the solid residue by magnetic separation, after which a product containing zinc oxide is separated by dielectric separation.

Abstract: A device for processing scrap rubber has a reactor with a screw conveyor disposed inside a heating chamber, a thermal decomposition unit, burners, a condenser, a cyclone filter, and devices for discharging solid residue and removing a gas-vapor mixture. The reactor has two sections connected in parallel. The thermal decomposition unit has screw conveyors in each section, the conveyors have axial heating pipes with a coil. Along the length of the conveyors plates are arranged at the corners of an equilateral triangle in contact with and perpendicular to the side surface of the heating tube. A cylinder furnace with an evaporator and a burner is connected to the ends of the pipes. An outlet of the condenser is connected to a liquid fraction separator, inlets of the coils are connected to an outlet of the evaporator, and an inlet of the evaporator is connected to an outlet from the separator.
