METHOD OF VACUUM DISTILLATES PROCESSING Russian patent published in 2017 - IPC C10G69/04 

FIELD: fuel.

SUBSTANCE: invention relates to of vacuum distillates processing method with production of Euro-5 class diesel fuel, used in cold and Arctic areas. Method includes stages of raw material hydrogenation refining and residue fraction catalytic cracking, produced from hydrogenation refining products, mixing of hydrogenation refining and catalytic cracking stages diesel distillates in ratio from 10:90 to 50:50 wt % and their combined hydro-fining. At that, produced at hydro-fining stage hydrogenation product is divided by fractionation into two fractions: light diesel fraction, boiling out within temperature range 140–300 °C, and remaining heavy diesel fraction boiling out at temperature up to 360 °C, then heavy diesel fraction is subjected to catalytic dewaxing at temperature of 320–400 °C, pressure of 3.0–10.0 MPa, raw material supply volumetric flow rate of 0.6–3.0 hour^-1 and further hydro-fining – dearomatizing at temperature of 300–400 °C, pressure of 3.0–10.0 MPa, raw material supply volumetric flow rate of 3.0–10.0 hour^-1.

EFFECT: disclosed method enables to increase output of diesel fuel.
