GAS OIL HYDRAULIC PROCESSING Russian patent published in 2018 - IPC C10G65/12 C10G7/00 

FIELD: technological processes.

SUBSTANCE: present invention relates to the gas oil hydraulic processing method, comprising: (a) gas oil contacting with the hydrogen and optionally the first diluent to produce the first liquid feeding stream, where the hydrogen is dissolved in the first liquid feeding stream; (b) bringing the first liquid feeding stream into contact with the first catalyst in the filled with liquid hydraulic processing reaction zone to produce the first effluent stream; (c) optionally returning the first effluent portion, which is used as the entire first diluent or part thereof in the stage (a); (d) in the separation zone, the dissolved gases separation from the first effluent portion, not returned to stage (c) with the separation product obtaining; (e) bringing the separation product into contact with hydrogen and optionally the second diluent with the second liquid feed stream formation, where the hydrogen is dissolved in the second liquid feeding stream; (f) contacting the second liquid feeding stream with the second catalyst in the filled with liquid hydrocracking reaction zone with the second effluent production; (g) optionally returning the second effluent portion, which is used as the entire second diluent or part thereof in the stage (e); and (h) in the distillation zone upstream or downstream relative to the hydrocracking reaction zone, one or more distillation products and heavy oil from (1) the first effluent non-recoverable portion separation, if the distillation zone is upstream the hydrocracking reaction zone in the process flow, or (2) the second effluent non-returnable portion if the distillation zone is downstream the hydrocracking reaction zone in the process flow. At that, the first catalyst is the hydraulic processing catalyst, and the second catalyst is the hydrocracking catalyst.

EFFECT: proposed method allows to produce diesel fuel with high yield.
