<p>Producing gasoline, and/or co-production of aromatic bases from one or more naphtha cuts, in which a charge (1) is sent to aromatic separation unit, comprises: producing cut extract (3), and a cut raffinate (2); sending the raffinate in catalytic reforming unit; producing gasoline cut having high octane index (4), where the gasoline is recycled towards the aromatic separation unit, or sent to aromatic complex unit by flow (6); sending all or part of the extract in aromatic complex unit to produce aromatic bases (7) and (8); and sending other part of the extract to gasoline pool. Process for producing gasoline having octane index of greater than 95, and/or co-production of aromatic bases from one or more naphtha cuts obtained from atmospheric distillation, fluid catalytic cracking (FCC), coking, steam cracking, hydrocracking, natural gas condensate fractionation, in which a charge (1) is sent to an aromatic separation unit, comprises: producing a cut extract (3) containing the majority of the aromatics, and a cut raffinate (2) containing the majority non-aromatic compounds; sending at least partly the raffinate in a catalytic reforming unit; producing a gasoline cut having high octane index (4) constituting a part of the gasoline pool, where the gasoline is wholly/partially recycled towards the aromatic separation unit, or wholly/partly sent to the aromatic complex unit by flow (6); sending all or part of the extract in an aromatic complex unit allowing to produce aromatic bases (7) and (8); and sending the other part of the extract to the gasoline pool.</p> |
