George E. Addison has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Selected aromatic hydrocarbon production
    Patent number: 4158025
    Abstract: Selected aromatic hydrocarbon concentrates -- benzene, mixed xylenes -- are produced by way of a combination process which involves catalytic reforming followed by dealkylation. Although the process affords flexibility respecting the precise aromatic concentrate produced, it is particularly directed toward the maximization of benzene.
    Type: Grant
    Filed: March 13, 1978
    Date of Patent: June 12, 1979
    Assignee: UOP Inc.
    Inventor: George E. Addison
  • Combination process for selected aromatic hydrocarbon production
    Patent number: 4158026
    Abstract: Selected aromatic hydrocarbon concentrates -- benzene, mixed xylenes, etc. -- are produced by way of a combination process which involves catalytic reforming followed by hot flash separation of a portion of the reformed product and dealkylation of the resulting hot flash liquid phase in admixture with a second portion of the reformed product. Although the process affords flexibility respecting the precise aromatic concentrate produced, it is particularly directed toward the maximization of benzene from normally liquid naphtha hydrocarbons boiling up to about 425.degree. F. (218.degree. C.).
