The present invention describes a process for regenerative reforming of gasolines, characterized by recycling at least a portion of the effluent from the catalyst reduction zone to the head of the last or penultimate reactor of the reaction zone. This arrangement can significantly improve the hydrogen balance of the unit and the production of reformate.

Process for pre-generative reforming of gasolines, comprising recycling at least a portion of the effluent from the catalyst reduction phase

A process for reforming a feed composed of one or more hydrocarbon cuts containing 9 to 22 carbon atoms which includes, at least one first step for reforming the feed in at least one reforming unit, during which a stream of hydrogen is produced and at least one first step for distillation of the effluent from the reforming unit in the presence of a reforming catalyst in order to obtain 4 cuts. The 4 cuts are, a liquefied petroleum gas cut (LPG) (A), a C-Ccut: naphtha (B), a C-Ccut: densified kerosene (C), and a C-Ccut: densified gas oil cut (D). The invention also concerns the device for carrying out this process.
