Abstract: The present invention describes a process for treating a feedstock obtained from a renewable source, comprising a step a) of hydrotreating said feedstock, a step b) of separation into at least a light fraction and at least a hydrocarbon liquid effluent, a step c) of removing at least a portion of the water from the hydrocarbon liquid effluent, a step d) of hydroconversion of at least a portion of the hydrocarbon 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 10 less than 5×10−5 and a step e) of fractionation of the effluent obtained from step d) to obtain at least a middle distillate fraction.
