Abstract

Cette invention concerne la modification de catalyseurs par dépôt à la surface de ces catalyseurs d'un agent dérivé d'un agent du type composé organométallique. Une telle modification permet d'obtenir un catalyseur à sélectivité accrue face aux alkylbenzènes para-substitués, tels que le para-xylène (PX), par réaction d'un composé aromatique tel que le toluène et/ou le benzène, avec un agent de méthylation sélectionné parmi l'hydrogène et le monoxyde de carbone et/ou le dioxyde de carbone et/ou le méthanol. L'utilisation de ces catalyseurs à sélectivité accrue permet la récupération d'alkylbenzènes para-substitués avec une sélectivité supérieure ou égale à 80 %, largement supérieure à la concentration d'équilibre de 24 %.
