Catalytic cracking process

Patent ·
OSTI ID:6113135
The process for cracking a hydrocarbon feedstock to produce lower boiling hydrocarbons which comprises contacting the hydrocarbon feedstock under catalytic cracking conditions with a catalyst comprising a zeolitic aluminosilicate which has a mole ratio of oxides in the dehydrated state of (0.8501.1)M/sub 2///sub n/O:Al/sub 2/O/sub 3/:xSiO/sub 2/. M is a cation having a valence of ''n''; x has a value greater than 6.0; the aluminosilicate has an x-ray powder diffraction pattern having at least the d-spacings of Table A and has extraneous silicon atoms in the crystal lattice in the form of framework SiO/sub 4/ tetrahedra; and the zeolitic aluminosilicate has been ion-exchanged to contain at least one Group III A cation per unit cell.
