    Type: Grant
    Filed: February 12, 1982
    Date of Patent: August 9, 1983
    Assignee: Phillips Petroleum Company
    Inventors: John S. Roberts, Brent J. Bertus, Dwight L. McKay, H. Wayne Mark
  • Patent number: 4324648
    Abstract: Deposits on a cracking catalyst are passivated by contacting the cracking catalyst with tin and at least one of phosphorus or sulfur.
    Type: Grant
    Filed: March 24, 1980
    Date of Patent: April 13, 1982
    Assignee: Phillips Petroleum Company
    Inventors: John S. Roberts, Brent J. Bertus, Dwight L. McKay, H. Wayne Mark
  • Patent number: 4279735
    Abstract: A used hydrocarbon cracking catalyst is treated with an antimony carbonate to passivate contaminating metals thereon, e.g., vanadium, iron and/or nickel. A process for cracking a hydrocarbon in the presence of the passivated catalyst is also disclosed.
    Type: Grant
    Filed: April 25, 1980
    Date of Patent: July 21, 1981
    Assignee: Phillips Petroleum Company
    Inventors: Brent J. Bertus, Dwight L. McKay, H. Wayne Mark
  • Patent number: 4257919
    Abstract: A passivating agent is added to a cracking catalyst which has not been previously treated with the passivating agent by mixing the untreated cracking catalyst with a refractory material which has been previously treated with a passivating agent. At least a portion of the passivating agent is transferred by inter-particle transfer from the treated refractory material to the untreated cracking catalyst.A passivating agent may also be recovered from a previously treated cracking catalyst which has become contaminated by contacting the contaminated cracking catalyst with a refractory material which has not previously been treated with the passivating agent. At least a portion of the passivating agent will transfer by inter-particle transfer from the contaminated catalyst to the refractory material while the contaminants on the contaminated cracking catalyst will not transfer.
    Type: Grant
