METHOD OF HYDROGENATIVE TREATMENT OF VACUUM DISTILLATE Russian patent published in 2017 - IPC C10G65/12 

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to oil refining, namely to a method of treatment of vacuum distillate. The method of hydrogenative treatment of vacuum distillate is suggested comprising soft hydrocracking of the vacuum distillate at hiher temperatures and pressure upon presence of a hydrocracking catalyst, with further separation of a specific diesel distillate and inconvertible residue, wherein the separated after soft hydrocracking inconvertible residue is divided to two flows, one flow in amount of 30-70 wt % is delivered to a stage of additional hydraulic cleaning, and then for mixing with initial vacuum distillate, and second flow amounting to 70-30 wt % is removed from the system as feed stock for catalytic cracking or lubricating oils production.

EFFECT: method of hydrogenative treatment of vacuum distillate ensuring possibility upon use of feed stock with increased finished boiling point (up to 560°C) to gain high yield - up to 60 wt % of diesel fuel EURO-5 (sulfur content below 0,001 wt %) and low sulfur feed stock for catalytic cracking and lubricating oils production.
