Abstract
A catalyst containing a IZM-2 zeolite and a specific content of alkali metal or alkaline-earth metal compounds, and a process for the isomerization of an aromatic C8 cut using the catalyst.
Claims9
A catalyst consisting of
- at least one IZM-2 zeolite containing silicon atoms and optionally aluminum atoms in an amount from 1 to 90% by weight, relative to a total mass of said catalyst;
- at least one matrix;
- at least one metal from group VIII of the Periodic Table of the Elements in an amount from about 0.01 to 5% by weight, relative to a total mass of said catalyst;
- and
- a total weight content of sodium in said catalyst is less than 200 ppm by weight and greater than 20 ppm by weight, relative to a total mass of the catalyst;
- wherein the at least one metal from group VIII of the Periodic Table of the Elements is platinum.
