Catalyst comprising at least one IZM-2 zeolite, and its use in the transformation of hydrocarbon feeds

摘要

A catalyst is described which comprises at least one IZM-2 zeolite and at least one matrix, said zeolite having a chemical composition expressed as the anhydrous base in terms of moles of oxides by the following general formula: XO2: aY2O3: bMnO, 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, a and b respectively representing the number of moles of Y2O3 and MnO; and a is in the range 0.001 to 0.5, b is in the range 0 to 1 and n is in the range 1 to 2. Said catalyst is used in various processes for the transformation of hydrocarbon feeds.
