METHOD FOR PROCESSING OIL RESIDUES Russian patent published in 2017 - IPC C10G67/04 C10G67/14 

FIELD: chemistry.

SUBSTANCE: method involves vacuum distillation of fuel oil with the extraction of the vacuum distillate and tar, deasphalting the tar with a hydrocarbon solvent, the further hydrogenation skimming of the mixture of vacuum distillate and deasphalting oil with obtaining a hydrogenation product which is separated by means of rectification into the petrol, diesel and residual fractions. The residual fraction of the hydrogenation product is directed to mixing with the raw material of hydrogenation skimming at the following ratio, wt %: vacuum distillate 40-80; deasphalting oil 10-30; the residual fraction of the hydrogenation product 10-30.

EFFECT: method allows to increase the output of light fractions, primarily the diesel fuel complying with EURO-5 standard.
