Abstract

A process for isomerizing an aromatic cut containing at least one aromatic compound containing eight carbon atoms per molecule, which includes bringing the aromatic cut into contact with a catalyst containing a zeolite with structure type EUO, which catalyst has been prepared by obtaining a zeolite with structure type EUO having an overall Si/Al atomic ratio in the range 5 to 45, a sodium content in the range 500 to 5000 ppm by weight, with a Na/Al ratio in the range 5% to 20% by mole, and thereafter performing the following:
