This patent describes a cracking catalyst comprising a zeolite aluminosilicate 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:x/SiO/sub 2/ ''M'' is a cation having a valence of ''n;'' ''x'' has a value greater than 6.0 to about 7.0, has an x-ray powder diffraction pattern having at least the d-spacing of Table A; has extraneous silicon atoms in the crystal lattice in the form of framework SiO/sub 4/ tetrahedra; an inorganic oxide matrix; has an effective amount between greater than zero to less than 5 weight percent, based on weight percent, based on the weight of the aluminoscilate employed in the catalyst, expressed as the oxide, of at least one rare earth cation selected from the group consisting of cerium, lanthanum, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium; and less than 1.2 weight percent Na/sub 2/O based on the wright of the aluminosilicate employed in the catalyst.
