ZEOLITHE IZM-2 BASED CATALYST WITH LOW ALKALINE CONTENT AND ITS USE FOR ISOMERIZATION OF C8 AROMATIC CUP

摘要

The present invention relates to a catalyst comprising at least one IZM-2 zeolite, at least one matrix and at least one metal from group VIII of the Periodic Table of the Elements, said catalyst being characterized in that the total weight content of alkaline elements and / or alkaline earth in said catalyst is less than 200 ppm by weight relative to the total mass of said catalyst, preferably less than 150 ppm, more preferably less than 100 ppm, preferably less than 90 ppm by weight, more preferably less than 85 ppm by weight more preferably less than 80 ppm by weight, very preferably less than 75 ppm by weight and even more preferably less than 70 ppm by weight and greater than 20 ppm by weight and preferably greater than 30 ppm by weight. The present invention also relates to a process for the isomerization of a cut containing at least one aromatic compound containing eight carbon atoms per molecule, said process comprising bringing said aromatic cut into contact with at least said catalyst according to the invention present in a catalytic reactor. The present invention relates to a catalyst comprising a zeolite designated under the name IZM-2 and a specific content of alkaline or alkaline earth compounds. The present invention also relates to a process for the isomerization of an aromatic C8 cut using said isomerization catalyst.
