This invention is an improved process for the conversion of a C9 mixed alkyl aromatic feedstream containing ethyl substituted aromatics to a product rich in toluenes and/or xylenes via catalytic transalkylation/disproportionation using a palladium loaded moderately, dealuminated mordenite catalyst in the presence of added hydrogen and benzene.

Cette invention est un procédé amélioré de conversion d'une charge d'alimentation aromatique d'alkyle mélangé à C¿9? contenant des fractions aromatiques à substitution éthyle, en un produit riche en toluènes et/ou xylènes par transalkylation/disproportion catalytique utilisant un catalyseur à mordénite désaluminé modérément chargé de palladium, en présence d'hydrogène et de benzène ajoutés.
