ABSTRACT:
The process for the catalytic cracking of a crude oil feedstock to produce lower boiling hydrocarbons which comprises contacting said feedstock with a zeolitic aluminosilicate which has a mole ratio of oxide in the dehydrated state of (0.85-0.1)M.sub.2
0:11.sub.2 O.sub.3 : x SiO.sub.2 wherein M is a cation having a valence of "n"; x has a value greater than 6.0: having a X-ray powder diffraction pattern having at least the d-spacings of Table A; having extraneous silicon atoms in the crystal lattice in the form of framework SiO.sub.4 tetrahedra, wherein said aluminosilicate has been ion-exchanged with Group IIIA cations. In addition, the Group IIIA exchanged LZ-210 may be heated for an effective temperature and for effective time in the presence of an effective amount of steam, and/or may be ion-exchanged with a multivalent cation other than Group IIIA, e.g. rare earth, to provide catalyst compositions.
