Abstract (en)

[origin: WO2022233561A1] The present invention describes a process for treatment of a feedstock derived from a renewable source, comprising a step a) of hydrotreating said feedstock, a step b) of separation into at least one light fraction and at least one hydrocarbon-based liquid effluent, a step c) of removal of at least one portion of the water from the hydrocarbon-based liquid effluent, a step d) of hydroconversion of at least one portion of the hydrocarbon-based liquid effluent, said hydroconversion step d) being characterized firstly by the use of a bifunctional catalyst comprising a molybdenum and/or tungsten sulfide phase promoted with nickel and/or cobalt, and secondly by a ratio between the partial pressure of hydrogen sulfide and of hydrogen at the inlet of the hydroconversion unit of less than 5x10-5 and a step e) of fractionation of the effluent from step d) to obtain at least one middle distillate fraction.
