Abstract

The invention describes a process for the production of middle distillate hydrocarbon bases from an ethanol feedstock that is produced from a renewable source that is obtained from biomass, comprising a stage for purification of said feedstock, a stage for dehydration of said purified feedstock into an effluent that is for the most part ethylene and comprises water, at least one stage for separating water, a first stage for oligomerization of the effluent that is for the most part ethylene into at least one olefinic effluent that comprises at least 80% by weight of olefins that have four or more carbon atoms, in the presence of a homogeneous catalyst that comprises at least one bivalent nickel compound, whereby a second oligomerization stage produces middle distillate hydrocarbon bases in the presence of an amorphous or zeolitic catalyst that has at least pore openings that contain 10 or 12 oxygen atoms, producing middle distillate hydrocarbon bases, and a fractionation stage.
