<p><P>PROBLEM TO BE SOLVED: To provide a hydrocracking and/or hydrotreatment process for producing a middle distillate in a high yield. <P>SOLUTION: This process uses a catalyst including an active phase containing at least one hydrogenating/dehydrogenating component selected from the group VIB elements and the non-precious elements of group VIII of the periodic table and a support including at least one dealuminated zeolite Y having an overall initial atomic ratio of silicon to aluminum of 2.5-20, an initial weight fraction of extra-lattice aluminum atoms greater than 10% based on the total weight of aluminum present in the zeolite, an initial mesopore volume measured by nitrogen porosimetry of greater than 0.07 mL/g, an initial crystal lattice parameter a<SB>0</SB>of 24.38-24.30Å, and the zeolite Y is modified by (a) a stage of basic treatment comprising mixing the dealuminated zeolite Y with a basic aqueous solution and at least one stage (c) of thermal treatment. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
