METHOD FOR HYDROGENATION PROCESSING OF VACUUM DISTILLATE Russian patent published in 2011 - IPC C10G65/12 

FIELD: chemistry.

SUBSTANCE: invention relates to a method for hydrogenation processing of vacuum distillate, involving mild hydrocracking of vacuum distillate at high temperature and pressure in the presence of a hydrocracking catalyst, followed by extraction of diesel distillate, where the diesel distillate extracted after the mild hydrocracking is split into two streams, one of which, in amount of 10-30 wt %, is taken for mixing with the initial vacuum distillate, and the other, in amount of 90-70 wt %, is taken for further hydrofining to obtain the desired diesel fuel.

EFFECT: reducing content of sulphur in the obtained diesel fuel to less than 50 ppm according to the Euro-4 standard and less than 10 ppm according to the Euro-5 standard.
