Abstract
La présente invention concerne un dispositif et un procédé de conversion de composés aromatiques, dans lequel : on extrait des composés aromatiques substitués en méthyles d’une charge hydrocarbonée (2) comprenant des composés aromatiques ayant au moins 8 atomes de carbone dans une unité d’extraction (1), pour produire au moins un effluent enrichi en composés aromatiques substitués en méthyles (3A, 3B) et un effluent appauvri en composés aromatiques substitués en méthyles (4) ; et on convertit en groupes méthyles des chaines alkyles en C2+ des composés aromatiques de l’effluent appauvri (4) dans une unité d’hydrogénolyse (5) disposée en aval de l’unité d’extraction (1), pour produire un effluent d’hydrogénolyse enrichi en composés aromatiques substitués en méthyles (7).
