FIELD: chemical technology.
SUBSTANCE: invention relates to a chemical method for processing waste of rubber-technical articles and domestic waste. Method involves depolymerization of the parent materials with addition of an organic solvent to obtain condensate and depolymerizate. Superheated organic solvent at temperature 200-500°C under pressure 0.1-0.3 bar is used as an organic solvent. Depolymerization is carried out by using gas torch forming in Laval's nozzle and representing products of high-temperature cracking of a mixture of organic solvent and depolymerizate. Part of depolymerizate is fed into furnace by high-pressure pump wherein it is heated to temperature 600-650°C and recovered to the depolymerization zone for high-temperature cracking through Laval's nozzle with separation for fractions. Invention provides simplifying technology and decreasing the cost in waste processing.
EFFECT: improved processing method.
