  • Catalytic cracking process
    Patent number: 4855036
    Abstract: Catalytic cracking processes wherein the cracking catalysts are prepared by: (1) 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 (2) ammonium exchanging the product of step (1) to provide a catalyst having less than 0.3 percent by weight Na.sub.2 O, based on total catalyst weight, or less than 2.0 percent by weight of the zeolite employed in the catalyst. Optionally, the zeolite used 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.
    Type: Grant
    Filed: December 18, 1987
    Date of Patent: August 8, 1989
    Assignee: UOP
    Inventors: Robert L. Chiang, Raymond G. Perigard, Jule A. Rabo
