Abstract
A process in which the paraffinic effluent derived from a Fischer-Tropsch synthesis unit is separated to obtain a heavy C+ fraction, said heavy fraction then being hydrogenated in the presence of a hydrogenation catalyst at a temperature in the rangeC to° C, at a total pressure in the rangetoMPa, at an hourly space velocity in the rangeto, and at a hydrogen flow rate corresponding to a hydrogen/hydrocarbons volume ratio in the rangetoNI/I/h, the liquid hydrogenated effluent then being brought into contact with a hydroisomerization/hydrocracking catalyst, with no prior separation step, the hydroisomerized/hydrocracked effluent then being distilled to obtain middle distillates and possibly oil bases.
