The invention concerns a process for producing middle distillates from effluents obtained from the Fischer-Tropsch process, comprising separating a heavy cut with an initial boiling point of 120-200° C., hydrotreating said cut and fractionating the hydrotreated cut to obtain at least one intermediate fraction and at least one fraction that is heavier than the intermediate fraction. The intermediate fraction boils between T1 and T2, T1 being in the range 120-200° C. and T2 being in the range 300-410° C. The heavy and intermediate fractions are treated over a hydrocracking/hydroisomerisation catalyst and the effluents obtained are distilled. The invention also concerns a unit.

This invention relates to a novel integrated method for economically processing vacuum residue from heavy crude oils. This is accomplished by utilizing a solvent deasphalter (SDA) in the first step of the process with a C3/C4/C5 solvent such that the DAO product can thereafter be processed in a classic fixed-bed hydrotreater or hydrocracker. The SDA feed also includes recycled stripper bottoms containing unconverted residue/asphaltenes from a downstream steam stripper unit.The asphaltenes from the SDA are sent to an ebullated-bed reactor for conversion of the residue and asphaltenes. Residue conversion in the range of 60-80% is achieved and asphaltene conversion is in the range of 50-70%. The overall residue conversion, with the DAO product considered non-residue, is in the range of 80 W %-90 W % and significantly higher than could be achieved without utilizing the present invention.
