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/n 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.
