9 Claims

1. 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
