    摘要： Process for the production of paraxylene from a C8 aromatic feedstock that comprises the following stages: A stage for separation by adsorption in a simulated moving bed SMB that produces an extract that contains at least 95% paraxylene and at least one raffinate R that contains ethylbenzene, A recycling of raffinate to the SMB separation stage after isomerization, in which R is separated in membrane separation means to obtain a first fraction F1 that is relatively high in ethylbenzene, which is purged, and an additional fraction F2 that is relatively low in ethylbenzene, which is recycled to the SMB after a single isomerization, preferably in the liquid phase.

    摘要： This invention relates to a process for the oligomerization of olefins that have 2 to 6 carbon atoms comprising at least: a) One reaction stage in which a first effluent that comprises oligomers, paraffins and olefins that have not reacted is recovered, b) A separation stage that makes it possible to separate a portion of the oligomers that are contained in the effluent from a mixture that comprises oligomers, paraffins and the olefins that have not reacted, c) A recycling of a portion of said mixture in the reaction stage, and d) A stage for membrane separation of another portion of said mixture so as to draw off a permeate that comprises at least 70% by weight of olefins and a retentate that comprises paraffins and oligomers, e) A stage for recovery of oligomers on the retentate.

    摘要： The invention relates to a process for converting a hydrocarbon charge of linear and branched olefins, comprises the following stages: a) a stage of membrane separation of the hydrocarbon charge under conditions making it possible to produce a cut β containing the majority of the linear olefins present in said charge, and a cut γ containing the majority of the branched olefins, b) a stage of treatment of the linear olefins contained in the effluents originating from the membrane separation stage (cut β) under moderate oligomerization conditions, c) a stage of distillation separation of the effluents originating from the oligomerization stage into at least two cuts, d) a stage of hydrogenation of the cut η under conditions for obtaining a gas oil with a high cetane number.
