Abstract
The invention relates to a process for producing middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis, implementing a hydrocracking/hydroisomerization catalyst comprising at least one hydro-dehydrogenating metal selected from the group formed by the metals from group VIB and from group VIII of the periodic table and a substrate comprising at least one crystallized IZM-2 solid having a chemical composition, expressed on an anhydrous base, in terms of oxide moles, by the following general formula: XO2:aY2O3:bM2/nO, wherein 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 valency n, a and b representing respectively the number of moles of Y2O3 and M2/nO and a is between 0 and 0.5 and b is between 0 and 1.
