Abstract
A process for producing a base for a fuel from a C2 ethanol feedstock, by a first stage for oligomerization of the feedstock into a hydrocarbon effluent that contains a mixture of olefins for the most part having between 4 and 30 carbons, and contains a C10-C24 fraction that has a mean linearity that is greater than 60%, in the presence of a homogeneous catalytic system that contains a metal precursor of titanium, zirconium, hafnium, nickel and/or iron, a second stage for oligomerization of a portion of the effluent that is obtained from stage a), into a hydrocarbon effluent that contains a mixture of olefins for the most part having between 4 and 30 carbon atoms, and containing a C10-C24 fraction that has a mean linearity that is less than 50%, in the presence of a homogeneous catalytic system.
