  • Novel alumina support materials
    Patent number: 5015614
    Abstract: Disclosed is a catalyst support material comprised of alumina and a modifier comprised of about 100 to 500 wppm Si and at least 10 wppm of one or more alkaline earth metals selected from Ca, Mg, Ba, and Sr wherein the total amount of modifier does not exceed 5000 wppm.
    Type: Grant
    Filed: July 3, 1989

    Assignee: Exxon Research and Engineering Company
    Inventors: William C. Baird, Jr., Ehsan I. Shoukry
  • Novel platinum-rhenium-alumina catalysts for reforming
    Patent number: 5013704
    Abstract: Disclosed is a catalyst for reforming gasoline boiling range naphthas which catalysts are comprised of Pt and Re on alumina and a modifier comprised of at least 100 to 500 wppm Si and 10 wppm of one or more alkaline earth metals selected from Ca, Mg, Ba, and Sr wherein the total amount of modifier does not exceed about 5000 wppm.
    Type: Grant
    Filed: July 3, 1989
    Date of Patent: May 7, 1991
    Assignee: Exxon Research and Engineering Company
    Inventors: William C. Baird, Jr., Ehsan I. Shoukry
  • Multistage reforming with interstage aromatics removal
    Patent number: 4975178
    Abstract: A process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock wherein the reforming is conducted in two or more stages wherein each stage is separated from another stage by aromatics removal from the reaction stream of a preceding stage. Reforming in at least one of the downstream reactors is conducted in the presence of a catalyst comprised of a nobel metal, an inorganic support, and a promotor metal; or a catalyst comprised of a Group VIII metal on a type-X, type-Y, or type-L zeolitic support.
    Type: Grant
    Filed: October 2, 1989
    Date of Patent: December 4, 1990
    Assignee: Exxon Research & Engineering Company
    Inventors: Kenneth R. Clem, Kenneth J. Heider, James E. Kegerreis, Ehsan I. Shoukry
  • Reforming with modified alumina catalysts
    Patent number: 4966682
    Abstract: A process for reforming naphtha and straight run gasoline feeds by contacting the feed, and hydrogen, with a supported platinum catalyst on an alumina support modified with at least about 100 wppm Si and at least 10 wppm of one or more alkaline-earth metal selected from Ca, Mg, Ba, and Sr, wherein the total amount of modifier does not exceed about 5000 wppm.
    Type: Grant
    Filed: July 3, 1989
    Date of Patent: October 30, 1990
    Assignee: Exxon Research & Engineering Company
    Inventors: William C. Baird, Jr., Ehsan I. Shoukry
  • Multistage reforming with interstage aromatics removal
    Patent number: 4872967
    Abstract: Disclosed is a process for catalytically reforming a gasoline boiling range hydrocarbonaceous feedstock wherein the reforming is conducted in two or more stages wherein each stage is separated from another stage by aromatics removal from the reaction stream of a preceding stage. The resulting aromatics-lean stream is passed to a downstream reforming stage.
