FIELD: oil-and-gas production.
SUBSTANCE: invention relates to method of wasteless treatment of oil tars in mixtures with donor-hydrogen admixture - shale oil by method of its thermal decomposition with receiving of desired product, raw material in the form of mixture of oil tar with shale oil is subject to thermal decomposition at temperatures 400-450°C at atmospheric pressure, herewith shale oil is taken in amount 6-66% , herewith desired products are gas, clear distillate products - components of engine fuel (gasoline, kerosenes, diesel-fuel oils) and thermal decomposition - residues, used in the capacity of sealing materials, rubbers' plasticiser, oil sintering additive, pecks, oil hydrocarbon deoxidising agent, semiproducts for receiving of oil-shale-chemical coke and carbon materials of different purposes.
EFFECT: increasing of target liquid products, particularly of engine fuel with providing of positive ecological properties.
