    摘要： A process for hydrocracking a crude oil feed, a hydrocracking catalyst employed therein, and a process for the preparation of this catalyst are disclosed. The hydrocracking catalyst comprises a zeolitic aluminosilicate which has an SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least 6 and which has been treated by (i) thermal treatment at an effective temperature and for an effective time in the presence of steam, followed by (ii) ion-exchange with a solution containing ammonium ion; and (2) an effective amount of a hydrogenation component. In a preferred embodiment, the starting crystalline zeolitic aluminosilicate is a Y-type zeolite having an SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least about 9 and a unit cell dimension (a.sub.o) of less than about 24.55 .ANG., and the steam treatment is carried out for a period sufficient to cause a decrease of not more than about 0.1 .ANG. in the unit cell dimension, thereby producing a Y-type zeolite product having a SiO.sub.2 /Al.sub.2 O.sub.3 molar ratio of at least about 9 and a unit cell dimension of less than about 24.45 .ANG..

    摘要： Catalytic cracking catalysts, the process of their preparation and the process of their use. The cracking catalyst comprises a zeolite having a mole ratio of oxides in the dehydrated state of (0.85-1.1) M.sub.2/n O:Al.sub.2 O.sub.3 :xSiO.sub.2 wherein "M" is a cation having a valence of "n", "x" has a value greater than 6.0, has a x-ray powder diffraction pattern having at least the d-spacings of Table A, has extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra and has been thermally treated and/or cation exchanged with a multivalent cation. The catalyst of the instant invention are unique in the fact that the zeolitic aluminosilicate has less than 1.2 weight percent Na.sub.2 O and such is achieved without the requirement of a pre-calcination step.
