Patents by Inventor Ronald P. Billings

Ronald P. Billings 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).

  • Fluid catalytic cracking
    Patent number: 4194965
    Abstract: In Fluidized Catalytic Cracking (FCC), the significant advantages of stripper cyclones in the reactor are enhanced by operating the regenerator in CO combustion mode.
    Type: Grant
    Filed: February 2, 1978
    Date of Patent: March 25, 1980
    Assignee: Mobil Oil Corporation
    Inventors: Ronald P. Billings, Ellen M. Hysell
  • Production of alkyl aromatic hydrocarbons
    Patent number: 3957621
    Abstract: Alkyl aromatic hydrocarbons useful as chemical raw material, solvents and the like are provided in high purity by hydrocracking of a fraction rich in alkyl aromatics and lean in aliphatic hydrocarbons over a particular zeolite catalyst associated with a hydrogenation/dehydrogenation component. The charge stock is characterized by substantial absence of benzene and lighter hydrocarbons. The technique is particularly well suited to production of maximum xylenes from a fraction containing higher boiling and lower boiling alkyl aromatics. Toluene derived from the hydrocracking reaction is disproportionated in the presence of hydrogen over a zeolite catalyst and the disproportionation effluent is processed through the same recovery train as the hydrocracked product.

    Abstract: Alkyl aromatic hydrocarbons useful as chemical raw material, solvents and the like are provided in high purity by hydrocracking of a fraction rich in alkyl aromatics and lean in aliphatic hydrocarbons over a particular zeolite catalyst associated with a hydrogenation/dehydrogenation component. The charge stock is characterized by substantial absence of hydrocarbons lighter than benzene. The technique is particularly well suited to production of maximum xylenes from a fraction containing higher boiling and lower boiling alkyl aromatics.
