Abstract
The invention relates to a process for conversion of a gasoline-range hydrocarbon feed into a gasoline fraction with a higher octane rating than that of the feedstream, and a gasoil fraction with a cetane number higher than 45, including the following steps: a) a membrane separation step (B) applied to the hydrocarbon feed under conditions enabling selective separation of the majority of the linear olefins present in said feed and constituting the β fraction, the fraction containing the majority of the branched olefins, termed the γ fraction, constituting a gasoline with a high octane rating, greater than that of the feed; b) an oligomerisation step (C) applied to the linear olefins (β fraction) contained in the effluent stream from the membrane separation step (B) under moderate oligomerisation conditions; c) a distillation separation step (D) applied to the effluent stream arising from the oligomerisation step in at least two fractions; d) a hydrogenation step (E) applied to one of the fractions obtained at step c).
