METHOD FOR OBTAINING LIQUID PRODUCTS DURING THERMAL DECOMPOSITION OF SOLID CARBON-CONTAINING RAW MATERIALS Russian patent published in 2022 - IPC C10G1/04 C10G49/14 

FIELD: thermal processing equipment.

SUBSTANCE: invention relates to the field of thermal processing of coal and is aimed at the production of gaseous, liquid products and carbon solid residue. The invention relates to a method for obtaining liquid products during the thermal decomposition of solid carbon-containing raw materials, in which the feedstock suitable for processing is sent to a pyrolyzer, where, at a maintained temperature of 450-475°C, in a liquid hydrogen-donating solvent, which is a condensed phase of pyrolysis of rubber waste (RW), the following products are formed: the gas phase of hydrocarbons, solid carbon residue, aqueous solutions of organic substances. Next, the solid carbon residue is sent to the extractor, where liquid products, maltenes and asphaltenes, are formed by sequential extraction action with n-hexane and benzene.

EFFECT: increase in the efficiency of the process, namely, the production of liquid products: maltenes and asphaltenes.
