ABSTRACT:
Catalytic cracking catalysts and catalytic cracking process wherein the cracking catalysts are prepared by: (i) contacting a mixture of a large pore zeolite and an inorganic oxide matrix at effective conditions of temperature, pH and time with a fluoro salt; and (ii) ammonium exchanging the product of step (i) to provide a catalyst having less than 2.0 percent by weight Na.sub.2 O, based on the weight of the zeolite. Optionally, the product is provided with an effective amount of at least one cation selected from the class consisting of cerium, lanthanum, praseodymium, neodymium, promethium, samarium, europium, lutetium, gadolinium, terbium, dysprosium, holmium, erbium, thulium and ytterbium.
