FIELD: oil and gas industry.
SUBSTANCE: crushed natural fuel mixed with oil slurries or acid tars, which are taken in the ratio of 1:1 to 5:1 by weight, is subject to heat treatment at temperatures of preferably 450-500°C in a drum-type reactor with external heating, which are heated with gas heat carrier so that gaseous fuel product, liquid products and solid coke-ash residue are obtained. Gaseous fuel product is supplied for combustion, and combustion flue gases of gaseous thermocracking products of raw mixture are used for heating of the drum-type reactor.
EFFECT: increasing yield of target product, enlarging range of residue oil raw material, and simplifying instrumentation.
