  • Tackifiers and a process to obtain tackifiers
    Patent number: 5652308
    Abstract: Novel tackifier resins having a M.sub.n of 5,000 or less and a T.sub.g of 0.degree. C. or above are produced by combining a metallocene catalyst with an alpha-olefin and a cyclic monomer. New adhesives are produced by blending the novel tackifier with a base polymer.
    Type: Grant
    Filed: July 21, 1995
    Date of Patent: July 29, 1997
    Assignee: Exxon Chemical Patents Inc.
    Inventors: Natalie Ann Merrill, James McLeod Farley, Martha Hetzel Robertson, Charles Lewis Sims, Richard Byron Pannell, Angelo Anthony Montagna
  • Hydrodesulfurization process employing a Group IV-B promoted catalyst
    Patent number: 4080286
    Abstract: An improved process for the hydrodesulfurization of hydrocarbons employing a catalyst comprising Group VI-B and Group VIII metals supported on a refractory oxide and promoted with a minor amount of titanium by contacting the refractory oxide with an aqueous solution of a titanium salt.
    Type: Grant
    Filed: October 20, 1976
    Date of Patent: March 21, 1978
    Assignee: Gulf Research & Development Company
    Inventors: Stephen Joseph Yanik, Angelo Anthony Montagna, James Albert Frayer
  • 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.
    Type: Grant
    Filed: December 29, 1976
    Date of Patent: November 8, 1977
    Assignee: Gulf Research & Development Company
    Inventors: Angelo Anthony Montagna, Allen Evarts Somers, Raynor Tyler Sebulsky
  • Hydrogenation process employing a zinc promoted catalyst
    Patent number: 4052296
    Abstract: An improved hydrogenation process for the denitrification and desulfurization of hydrocarbons employing a catalyst consisting essentially of a Group VI-B metal, nickel and zinc composited with alumina.
