Abstract:
A process for isomerization of a feedstock containing aromatic compounds having eight carbon atoms, said process comprising (a) conduct least one isomerization stage carried out at a temperature of 320Â° C. to 400Â° C., and in the presence of a catalyst containing at least one metal of group VIII, said catalyst having been activated according to an activation process comprising at least one sulfurization stage and at least one passivation stage with ammonia or with an ammonia precursor, to obtain an effluent containing 10 to 30%, by mass of the outlet effluent, naphthenes with eight carbon atoms, and (b) conducting with the outlet effluent of the at least one isomerization stage at least one dehydrogenation stage.
