    • The invention relates to the field of processing of raw materials from rubber products, mainly recycled tires.The method of obtaining carbon-containing material from recyclable tires or rubber products, including: mechanical crushing of raw materials from recycled tires or rubber products in a shredder; supplying the charge to the reactor and pyrolysis at the temperature of the pyrolysis of rubber with the formation of vapor-gas products and a solid residue; continuous removal of gaseous pyrolysis products from the reactor, followed by condensation of liquid products into the condensation column of liquid fractions, unloading of solid residue from the reactor and its cooling; feeding the cooled residue to the crusher; rough crushing of solid residue; removal of metal from the crushed solid residue in a magnetic separator, characterized in that before mechanical crushing, metal bead rings are removed from recycled tires; before feeding the charge into the reactor, an inhibitor of coke formation is introduced in the amount of 3-20% by weight of the charge and consisting of the solid component of the coke formation inhibitor, which is any combination of thermoplastic linear polymers from the group: polyethylene, polypropylene, polyethylene terephthalate, polystyrene and the liquid component of a coke-formation inhibitor - polymethylsiloxane, in the amount of 0.5 - 1.0% by weight of the inhibitor; the pyrolysis of the charge in the reactor is carried out at a pyrolysis temperature of 350 °C in the main working zone of the reactor, to 600 °C at the exit of the reactor; the removal of metal from the crushed solid residue in the magnetic separator is performed until the metal content is not more than 0.1% of the total mass of the solid residue, after which the solid residue is processed and activated with superheated steam at a temperature of 250-350 °C in the steam chamber and the activated solid residue is crushed on a vortex the mill; two-stage classification of solid residue is carried out: at the air-through separator, from which the fine fraction is sent for further fine classification into the electric mass classifier, and the large fraction - screening is sent to the bunker and further or to the thermal furnace, which removes residual carbon and get additional the product is a mineral component, or sent for re-grinding into a vortex mill, where the fine fraction of the solid residue in the electrical mass classifier is divided into fraction F1, less than 45 µm (F1 45 µkm); returning the solid residue powder of the F2 fraction to more than 45 µkm (F2> 45 µkm) from the electrical mass classifier for repeated fine grinding in a vortex mill; the powder fraction F1 less than 45 µm (F1
