  • Catalytic pour point reduction of petroleum hydrocarbon stocks
    Patent number: 4057488
    Abstract: The pour point reduction of petroleum hydrocarbon stocks is obtained by the process of reducing the nitrogen concentration of the petroleum hydrocarbon stock to an acceptable level and thereafter contacting the petroleum hydrocarbon stock in the presence of hydrogen with a catalyst comprising titanium and a Group VIII noble metal on a decationized crystalline mordenite support under pour point reduction conditions of temperature, pressure and space velocity.
    Type: Grant
    Filed: November 2, 1976
    Date of Patent: November 8, 1977
    Assignee: Gulf Research & Development Company
    Inventors: Angelo Anthony Montagna, Allen Evarts Somers, Stephen Luther Peake, Sun Woong Chun
  • Process for producing a transformer oil having lower pour point and improved oxidation stability
    Patent number: 4057489
    Abstract: Transformer oils having pour points below -40.degree. F. (-40.00.degree. C.) are produced by the process of reducing the nitrogen concentration of a petroleum hydrocarbon feed stock, contacting the denitrogenated product with a catalyst comprising a Group IV-B metal and a Group VIII noble metal on a decationized crystalline mordenite support under pour point reduction conditions of temperature, pressure and space velocity, and thereafter passing the product of the pour point reduction step to a lubricating oil oxidation stability step.
