FIELD: chemistry.
SUBSTANCE: invention relates to method of increasing quality of residue of distillation of hydrocarbons, including hydrocracking of residue at the first stage of reaction with formation of flow, output from the first stage; hydrocracking of de-asphalted oil at the second stage of reaction with formation of flow, output from the second stage; fractioning of flow, output from the first stage, and flow, output from the second stage, with extraction of, at least, one distillate hydrocarbon fraction and residual hydrocarbon fraction, supply of residual hydrocarbon fraction into installation of de-asphalting with solvent and obtaining fraction of asphaltenes and fraction of de-asphalted oil.
EFFECT: higher total conversion of residue with reduction of catalyst introduction rate and quantity of consumed hydrogen.
