PROCESS FOR PRODUCING MIDDLE DISTILLATES BY HYDROCRACKING OF FEEDSTOCKS RESULTING FROM THE FISCHER-TROPSCH PROCESS IN THE PRESENCE OF A CATALYST COMPRISING AN IZM-2 SOLID

摘要

The invention relates to a process for producing middle distillates from a paraffinic feedstock produced by Fischer-Tropsch synthesis, using a hydrocracking/hydroisomerization catalyst that comprises at least one hydro-dehydrogenating metal chosen from the group formed by the metals of group VIB and of group VIII of the Periodic Table and a support comprising at least one IZM-2 crystalline solid having 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 represents at least one trivalent element and M is at least one alkali metal and/or alkaline-earth metal of valency n, a and b respectively representing the number of moles of Y2O3 and M2/nO and a is between 0 and 0.5 and b is between 0 and 1.
