- 63 - CATALYTIC CRACKING CATALYST AND PROCESS ABSTRACT Catalytic cracking catalysts, the process of their preparation and the process of their use. The instant process relates to a process for crack- ing a hydrocarbon feedstock to produce lower boiling hydrocarbons which comprises contacting said hydrocarbon feedstock with a zeolitic aluminosilicate which has a mole ratio of oxide in the dehydrated state of (0.85-1.1)M2/n0.A12O3: X SiO2 wherein M is a cation having a valence of "n": X has a value greater than 6.0; the aluminosilicate 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 SiO4 tetrahedra; and said zeolitic aluminosilicate has been treated with an effective amount of at least one Group IIIA cation.
