FIELD: chemistry.
SUBSTANCE: in method of obtaining distillates and residues for oil bases from hydrocarbon charge: a) charge is subjected to cracking in presence of hydrogen and hydrocracking catalyst, at least, in one reactor with boiling layer with possibility of conversion, at least, of 10 wt % of charge fraction, boiling at temperature over 370°C, into compounds with boiling point lower than 370°C; b) at least, part of effluent, obtained at stage a), is fractioned for isolation of, at least, first residue, at least, 85 wt % of whose compounds start boiling at temperature 320°C, said first residue containing aromatic compounds; c) at least, part of aromatic compounds from, at least, part of first residue is removed in order to obtain effluent with low content of aromatic compounds, content of aromatic compounds being less than 30 wt %; d) at least, part of effluent, obtained at stage c) is fractioned in order to isolate second residue for oil bases with output , at least, 15 wt % with respect to charge.
EFFECT: possibility to combine production of high-quality lubricating oils with performing preliminary cracking in reactor with boiling layer.
