The invention relates to a method for producing middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis, using a hydrocracking / hydroisomerization catalyst comprising at least one hydro-dehydrogenating metal selected from the group consisting of Group VIB and Group VIII metals of the Periodic Table and a carrier comprising at least one crystalline solid IZM-2 having a chemical composition, expressed on an anhydrous basis, in terms of moles of oxides, by the following general formula: XO2 where X represents at least one tetravalent element, Y represents at least one trivalent element and M is at least one alkali metal and / or an alkaline earth metal of valence n, a and b respectively representing the number moles of Y2O3 and M2 / n0 and a is 0 to 0.5 and b is 0 to 1. |
