Abstract
The invention relates to a catalyst for isomerization of a C8 aromatic cut containing a mordenite characterized in that said mordenite contains at least one metal of groups IIa, IVb, IIb or IVa and is such that: PA1 its overall Si/Al atomic ratio is between 6 and 15, PA1 its sodium content by weight relative to the weight of dry mordenite is less than 2000 ppm, PA1 its elementary mesh volume is between 2.725 and 2.785 nm.sup.3, PA1 its n-hexane adsorption capacity is greater than 0.065 cm.sup.3 of liquid/gram, PA1 its isooctane adsorption capacity is less than 0.068 cm.sup.3 of liquid/gram. The invention also relates to the preparation of this mordenite by grafting on an H-shaped mordenite of at least one organometallic compound of said metal.
