For the solution of the problem of rubber waste utilization the method of their thermal processing together with fine-grained oil shale in the solid heat carrier unit can be used. Thermal decomposition of oil shale and rubber scraps is carried out in the conditions of continuous mixing with hot heat-carrier ash in a rotary drum reactor. Combustion heat of the solid residue from the reactor (semicoke) is used in the furnace for regeneration of the heat carrier. Due to alkaline properties of oil shale ash a part of harmful sulfur compounds such as hydrogen sulfide in the retort gas and sulfur dioxide in the stack gas are bound by the ash residue.
