  • Conversion of olefins using improved catalysts
    Patent number: 3988384
    Abstract: Supported olefin conversion catalysts are activated by a method which comprises calcining the catalyst, impregnating the calcined catalyst with an alcoholic solution of an alkali metal salt, an alkali metal base or an alkali metal alcoholate and then recalcining the catalyst.
    Type: Grant
    Filed: December 3, 1974
    Date of Patent: October 26, 1976
    Assignee: Deutsche Texaco Aktiengesellschaft
    Inventors: Martin Cherubim, Elmar Wilms, Hans Arendsen
  • Separation of unsaturated compounds from liquid hydrocarbon mixtures containing same
    Patent number: 3979280
    Abstract: Unsaturated hydrocarbons are separated from liquid mixtures containing same by adsorbing the unsaturated compound using a metal-loaded macroporous exchange resin and desorbing the unsaturated compound using a normally gaseous hydrocarbon.
    Type: Grant
    Filed: December 12, 1974
    Date of Patent: September 7, 1976
    Assignee: Deutsche Texaco Aktiengesellschaft
    Inventors: Maximilian Dielacher, Uwe Hansen
  • Production of lubricating oils
    Patent number: 3970543
    Abstract: Lubricating oils are prepared by a sequence of steps comprising hydrorefining, fractionation and blending.
    Type: Grant
    Filed: October 2, 1974
    Date of Patent: July 20, 1976
    Assignee: Texaco Inc.
    Inventor: Herbert A. McIntosh
  • Preparation of refrigeration oils
    Patent number: 3953319
    Abstract: Refrigeration oils are prepared by subjecting a crude lubricating oil fraction to mild hydrogenation, acid treating, dewaxing and clay percolation.
    Type: Grant
    Filed: September 9, 1974
    Date of Patent: April 27, 1976
    Assignee: Texaco Inc.
    Inventors: Ralph P. Chesluk, Howard J. Platte, Edward C. Brink, Jr.
  • Cracking-isomerization process
    Patent number: 3953320
    Abstract: The octane number of a hydrocarbon fraction boiling below 425.degree.F is improved by a cracking-isomerization procedure. The C.sub.5 + portion of the resulting product may be used as a motor fuel or as a blending component for motor fuels.
    Type: Grant
    Filed: May 16, 1974
    Date of Patent: April 27, 1976
    Assignee: Texaco Inc.
    Inventors: Reese A. Peck, Li C. Mih, John T. Brandenburg
  • Method of hydrodesulfurizing heavy petroleum fraction in the initial stage of the on-stream period
    Patent number: 3953321
    Abstract: A desulfurization catalyst is activated by being heated to a temperature between about 750.degree. and 850.degree.F. in the presence of the charge stock to be desulfurized during the initial stages of the on-stream period. In a preferred embodiment the catalyst, prior to the heat treatment, is sulfided at a low temperature and low pressure. The resulting catalyst effectively desulfurizes a petroleum hydrocarbon charge stock with reduced hydrogen consumption.

  • Desulfurization process
    Patent number: 3933623
    Abstract: The deactivation rate of a catalyst used for the high temperature, high space velocity desulfurization of heavy oils is reduced by the incorporation in the catalyst of a small amount of a noble metal.
