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

摘要

FIELD: chemistry.;SUBSTANCE: in method applied is catalyst of hydrocracking/hydroisomerisation, which contains hydrogenation-dehydrogenation metal, selected from group, formed from metals of VIB group and group VIII of periodic table of elements, and substrate, which contains, at least, one crystalline solid IZM-2. Chemical composition of IZM-2, expressed in moles of oxides, in water-free condition corresponds to general formula: XO₂:aY₂O₃:bM_2/nO, where X stands for, at least, one trivalent element, and M is, at least, one alkaline and/or alkaline-earth metal with n valence, and a and b stand for, respectively, number of moles of Y₂O₃ and M_2/nO, and a constitutes from 0 to 0.5, and b constitutes from 0 to 1.;EFFECT: invention makes it possible to increase quantity of available middle distillates.;16 cl, 5 dwg, 3 tbl, 3 ex
