UTILIZATION OF RUBBER WASTE IN MIXTURE WITH OIL-SHALE IN DESTRUCTIVE THERMAL-PROCESSING USING THE METHOD OF SOLID HEAT CARRIER

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