Abstract:
1. A process for the isomerization of a feed comprising aromatic compounds containing 8 carbon atoms per molecule and at least ethylbenzene, in the presence of a catalyst comprising at least one zeolite with structure type EUO at least partially in acid form, at least one metal from group VIII of the periodic classification of the elements, and at least one binder, said process comprising: a) reducing the catalyst; b) activating the catalyst by bringing said catalyst into contact with said feed at a temperature in the range 450° C. to 600° C., limits included, a partial pressure of hydrogen in the range 2 to 45 bar, limits included, a total pressure in the range 5 to 50 bar, limits included, and at a space velocity in the range 0.25 to 30 h c) introducing water into said feed in a quantity in the range 50 ppm to 8000 ppm; d) bringing the feed containing water from step c) into contact with the catalyst activated in step b) under isomerization conditions.
