Abstract
The present invention relates to a process for isomerizing aromatic C8 cuts in the presence of a catalyst containing a mordenite which is slightly or not dealuminated and a binder. This mordenite is generally present at least in part in its acid form and its Si/Al atomic ratio is less than 20, preferably in the range 5 to 15, and more preferably in the range 5 to 10. The catalyst also contains at least one metal from group VIII of the periodic table, preferably selected from the group formed by palladium and platinum. Finally, the catalyst further contains at least one metal from group III of the periodic table, namely gallium, indium or thallium, preferably indium, and optionally at least one metal from group IV of the periodic table, namely germanium, tin or lead, preferably tin. The present invention also relates to the catalyst used in the isomerization process and to a process for its preparation.
