The invention relates to a process for the production of aromatic compounds from a hydrocarbon fraction with a catalyst the preferably circulates in a moving bed. In the process, a hydrocarbon feedstock that is treated by a hydrogen-rich gas is transformed. In a particular embodiment, regenerative reforming is conducted, such as for production of BTX (butene, toluene, xylenes) with continuous regeneration of the catalyst. The invention also pertains to the related device for carrying out the process.

Process and device for the production of aromatic compounds including a reduction of the catalyst

A moving bed process for producing aromatic compounds comprises at least a first step in which principally naphthene dehydrogenation is carried out in the presence of hydrogen in a mole ratio (H ) /(HC), said step being followed by at least one subsequent step carried out at a mole ratio (H ) /(HC) , the process also comprising reducing the catalyst with hydrogen in a ratio (H ) /(HC). In accordance with the invention, (H ) /(HC)&plus;(H ) /(HC)&lE;(H ) /(HC) , (HC) representing the molar quantity of feed in the first step and (HC) that of the subsequent step, or (H ) /(HC)&plus;(H ) /(HC)>(H ) /HC , but where (H ) /(HC) is less than (H ) /(HC) . Particular application to reforming.

Process for catalyst preparation

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.

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.
