FIELD: coal processing industry.
SUBSTANCE: invention relates to integrated thermochemical processing of carbon-containing crude, e.g. coal and shale oils, to produce various-composition liquid hydrocarbons useful as different-destination fuels (starting material for hydrogenation, ashless high-boiling extracts for combustion, etc.) as well as products for other purposes such as road-building bitumens and starting material for electrode coke. Process is conducted at elevated temperature and pressure in presence of distillate solvent boiling away at 350°C and activation additive, said solvent further containing petroleum-, coal-, and shale oil-origin residual fractions having boiling temperature up to 350°C in amount 10 to 50 wt %.
EFFECT: increased yields of liquid products to 80-90%.
