  • Process for the manufacture of furan compounds
    Patent number: 4323508
    Abstract: The present invention relates to a process for the manufacture of furan compounds by the direct oxidation of conjugated diolefins with air or oxygen in the liquid phase in the presence of a transition metal catalyst system.
    Type: Grant
    Filed: February 2, 1979
    Date of Patent: April 6, 1982
    Assignee: The Standard Oil Company
    Inventors: Daniel R. Herrington, Albert P. Schwerko
  • High-surface area coated support for catalysts and process for their preparation
    Patent number: 4293449
    Abstract: A method for preparing a high-surface area catalyst consisting of high-surface area support material coated on an inert core. The inert core is partially wetted with a wetting agent and a powdered, high-surface area coating is then applied to the core. The coated core can be dried and calcined, and additional catalytic elements can be added by impregnating the core with solutions containing such elements.
    Type: Grant
    Filed: August 7, 1980
    Date of Patent: October 6, 1981
    Assignee: The Standard Oil Company
    Inventors: Daniel R. Herrington, Albert P. Schwerko
  • Hydrogen processing of hydrocarbon feeds using coated catalysts
    Patent number: 4255253
    Abstract: Catalysts consisting of a base support having a strongly adherent outer coating of an active catalytic material have been found to give superior results in known hydrogen processing reactions wherein sulfur, nitrogen and the metal content of a hydrogen feedstock are reduced.
    Type: Grant
    Filed: January 3, 1979
    Date of Patent: March 10, 1981
    Assignee: The Standard Oil Company
    Inventors: Daniel R. Herrington, Albert P. Schwerko, Serge R. Dolhyj, Wilfrid G. Shaw
  • Dehydration of water soluble monomers with liquid carbon dioxide
    Patent number: 4253948
    Abstract: Separation of certain water soluble organic monomers such as acrylic acid from an aqueous solution can be accomplished by extraction with carbon dioxide, crystallizing the extract to remove carbon dioxide hydrate, and flashing off the remaining carbon dioxide solvent from the extract.
    Type: Grant
    Filed: May 14, 1979
    Date of Patent: March 3, 1981
    Assignee: Standard Oil Company
    Inventors: Harley F. Hardman, Albert P. Schwerko
  • Hydrotreating process utilizing elemental sulfur for presulfiding the catalyst
    Patent number: 4177136
    Abstract: The present invention relates to an improved method of catalyst presulfiding, wherein the catalyst is treated with elemental sulfur. The use of elemental sulfur as a catalyst presulfiding agent is a means of rapidly and reproducibly attaining a highly active catalyst.
    Type: Grant
    Filed: May 12, 1978
    Date of Patent: December 4, 1979
    Assignee: The Standard Oil Company (Ohio)
    Inventors: Daniel R. Herrington, Albert P. Schwerko
  • Amphora aggregates and the process for their preparation
    Patent number: 4170569
    Abstract: Improved amphora aggregates having a substantially spherical shape, a void center and two cavities 180.degree. apart in the external surface communicating to the void center are useful in diffusion-limited reactions and/or reactions in which heat transfer is critical. Especially preferred is use of the amphora aggregates in the hydrotreating of light hydrocarbon fractions, catalytic reforming, and fixed-bed alkylation processes.
