Catalyst comprising an izm-2 zeolite and at least one metal, and its use in the transformation of hydrocarbons

摘要

A catalyst is described which comprises at least one IZM-2 zeolite, at least one matrix and at least one metal selected from metals from groups VIII, VIB and VIIB, said zeolite having a chemical composition expressed as the anhydrous base in terms of moles of oxides by the following general formula: XO2:aY2O3:bM2/nO, in which X represents at least one tetravalent element, Y represents at least one trivalent element and M is at least one alkali metal and/or alkaline-earth metal with valency n, a and b respectively representing the number of moles of Y2O3 and M2/nO; and a is in the range 0.001 to 0.5 and b is in the range 0 to 1.
