  • Patent number: 5348927
    Abstract: A method of removing chloride from phosphorus/vanadium/oxygen mixed oxide oxidation catalysts comprising treating a chloride containing catalyst comprising phosphorus, vanadium and oxygen with a stream of gas comprising oxygen, steam and an inert gas at flow rate and temperature and for a period of time to substantially reduce the amount of chloride in the catalyst.
    Type: Grant
    Filed: March 1, 1993
    Date of Patent: September 20, 1994
    Assignee: Scientific Design Company, Inc.
    Inventor: Arie Bortinger
  • Patent number: 5296436
    Abstract: An improvement in the oxidation catalyst used for the partial oxidation of n-butane and containing vanadium and phosphorus, zinc, lithium and molybdenum mixed oxides which comprises adding the molybdenum as a compound which is dissolved in a solvent during the manufacture of the catalyst.
    Type: Grant
    Filed: January 8, 1993
    Date of Patent: March 22, 1994
    Assignee: Scientific Design Company, Inc.
    Inventor: Arie Bortinger
  • Patent number: 5280003
    Abstract: An improvement in the oxidation catalyst used for the partial oxidation of n-butane and containing vanadium and phosphorus, zinc, lithium and molybdenum mixed oxides which comprises carrying out the crystallization step under static conditions which allows for more uniform conditions for crystal growth. The static conditions are maintained by refluxing the solvent during the period of crystallization.

    Date of Patent: January 18, 1994
    Assignee: Scientific Design Company, Inc.
    Inventor: Arie Bortinger
  • Patent number: 4851605
    Abstract: A process for preparing a zeolite, e.g. ZSM-5, under controlled conditions of pH adjustment with an acid; SiO.sub.2 /Al.sub.2 O.sub.3 mole ratio, and in the substantial absence of alkali metal cations, is disclosed, as well as a process for using the same to synthesize olefins from methanol and/or dimethyl ether.
    Type: Grant
    Filed: July 13, 1984
    Date of Patent: July 25, 1989
    Assignee: Exxon Research & Engineering Co.
