Catalyst comprising: - a support that includes at least one crystallized solid IZM-2 presenting a diffraction diagram of the X-rays that includes at least the stripes inscribed in the following table: ** Table ** - where FF> = very strong ; F> = strong; m> = medium; mf> = weak medium; f> = weak; ff> = very weak, and presenting a chemical composition, expressed on an anhydrous basis, 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 it represents at least one trivalent element and M is at least one alkali metal and / or an alkaline earth metal of Valencia n, representing a and brespectively the number of moles of Y2O3 and M2 / nO, is already between 0 and 0.5 and b is between 0 and 1, and - an active phase containing at least one hydro-dehydrogenating element of group VIB and / or at least one non-noble hydrohydrogenating element of group VIII of the periodic classification, said catalyst being a sulfide phase catalyst. |
