FIELD: petroleum processing.
SUBSTANCE: invention relates to technologies of obtaining feedstock sources such as crude oil, high-boiling petroleum fractions, petroleum residues, coal liquefaction and by-product-cock plant products, spent lubricating oils, household and industrial wastes of various hydrocarbon fuels, and hydrocarbon raw materials for basic and petrochemical synthesis. Method according to invention comprises: provision and/or synthesis hydrogen donors; hydrocarbon, hydrogen donor, and catalyst stirring step; separation of resulting mixture; isolation of light and heavy fractions; and recycling of heavy fraction together with catalyst to mixing step and hydrogenation of light fraction followed by recovering synthesized hydrogen donors, which are also directed to mixing step.
EFFECT: enhanced process efficiency.
