摘要： For producing three effluents which are respectively rich in straight chain paraffins, in mono-branched paraffins, and in di-branched and tri-branched paraffins possibly with naphthenic and/or aromatic compounds, from C5-C8 cuts or intermediate cuts (C5-C7, C6-C8, C7-C8, C6-C7, C7 or C8), comprising paraffinic and possibly naphthenic and/or aromatic hydrocarbons, and in some cases olefinic hydrocarbons, a chromatographic separation process uses a separation zone operating by adsorption. The process of the invention is of particular application when coupled with a hydro-isomerization process, which selectively recycles straight chain and mono-branched paraffins, necessary for paraffins containing at least 7 carbon atoms.

摘要： The invention provides a high octane number gasoline pool comprises at least 2% of di-branched paraffins containing 7 carbon atoms, and a process for producing this gasoline pool by hydro-isomerizing a feed constituted by a C5 to C8 cut which comprises at least one hydro-isomerization section and at least one separation section, in which the hydro-isomerization section and at least one separation section, in which the hydro-isomerization section comprises at least one reactor. The separation section comprises at least one unit and produces at least two streams: a first stream which is rich in di- and tri-branched paraffins, and possibly in naphthenes and aromatic compounds which is sent to the gasoline pool; and in a first version of the process, a second stream is produced which is rich in straight-chain and mono-branched paraffins which is recycled to the inlet of the hydro-isomerization section, while in a second version of the process, a second flux is produced which is rich in straight-chain paraffins which is recycled to the inlet of a first hydro-isomerization section and a third stream is produced which is rich in mono-branched paraffins which is recycled to the inlet of a second hydroisomerization section.

摘要： A simultaneous process for simulated moving-bed dismutation and separation of a toluene feedstock into benzene and xylenes in the presence of a hydrogen-rich desorbent in at least one adsorber-reactor (100) that contains beds of a solid and comprises at least three zones (23, 24, 25) is described. Vapor-phase or supercritical feedstock (1) is introduced at the inlet of a reaction and adsorption zone (25) (zone III), and a raffinate (15) that is high in benzene and desorbent is recovered at the outlet. Desorbent (5, 7) is introduced at the inlet of a desorption zone (23) (zone I), and an effluent from which is drawn off a portion (8) in the form of an extract that is high in xylenes and desorbent is recovered at the outlet. The other portion of the effluent of zone I is introduced at the inlet of a reaction and desorption zone (24) (zone II), and an effluent is recovered at the outlet that is sent back to the inlet of reaction and adsorption zone III. Each of the zones comprises at least one bed that contains an adsorbent that is adapted to separate benzene, toluene and xylenes, and a catalyst that is adapted to dismutate toluene into benzene and xylenes, whereby the adsorbent and the catalyst are in solid form.

摘要： For producing three effluents which are respectively rich in straight chain paraffins, in mono-branched paraffins, and in di-branched and tri-branched paraffins possibly with naphthenic and/or aromatic compounds, from C5-C8 cuts or intermediate cuts (C5-C7, C6-C8, C7-C8, C6-C7, C7 or C8), comprising paraffic and possibly naphthenic, aromatic and olefinic hydrocarbons, the separation process of the invention uses at least two separation units operating either by adsorption or by permeation. It is of particular application when coupled with a hydro-isomerization process, which selectively recycles straight chain and mono-branched paraffins, necessary with paraffins containing more than 7 carbon atoms.
