The present invention concerns a process for the production of gasoline with an octane number and for the co-production of aromatic bases, starting from a naphtha cut (1) comprising paraffins and naphthenes, the process comprising the following steps: a) sending the naphtha cut (1) to a first catalytic reforming unit (2) in order to convert at least a portion of the paraffins and/or naphthenes into aromatic compounds and to produce hydrogen; b) withdrawing a first effluent (3) and a stream of hydrogen (4) from the first catalytic reforming unit (2); c) sending the first effluent (3) to an aromatics separation unit (5) so as to separate a first aromatic cut and a raffinate (7) containing unconverted naphthenes and/or paraffins; d) sending the raffinate (7) to a second catalytic reforming unit (9) so as to convert the unconverted naphthenes and/or paraffins into aromatic compounds and to produce hydrogen; e) withdrawing a reformate (11) containing aromatic compounds and a stream of hydrogen (10) from the second catalytic reforming unit (9).
