  • Surface treated permeable inorganic membranes and method of making same
    Patent number: 4957890
    Abstract: A treated permeable inorganic membrane having good chemical stability over a pH range of from 1 to 14. The monomolecular layer of organic acid material is formed on the membrane surface by contacting phosphonic acid having the formula RPO(OH).sub.2 ; phosphinic acid having the formula RR'PO(OH); monocarboxylic acids having the formula RCOOH; dicarboxylic acids having the formula R"(COOH).sub.2 ; or boronic acid having the formula RB(OH).sub.2.
    Type: Grant
    Filed: October 31, 1988
    Date of Patent: September 18, 1990
    Assignee: Aluminum Company of America
    Inventors: Larry F. Wieserman, Karl Wefers, Kathryn Cross, Edward S. Martin, H. Philip Hsieh, William H. Quayle
  • Method of making filament growth composite
    Patent number: 4892693
    Abstract: A composite and a process for forming it are provided, said process comprising providing a substrate bearing crystalline and preferably single crystal filaments as growths on the substrate and forming a solid matrix encompassing the filaments. The composites are useful for aircraft, boat and auto skins and structural members.
    Type: Grant
    Filed: July 24, 1987
    Date of Patent: January 9, 1990
    Assignee: Aluminum Company of America
    Inventors: Anthony J. Perrotta, Donald K. Grubbs, William H. Quayle, Thomas B. Gurganus
  • Catalyst for hydroconversion of heavy oils and method of making the catalyst
    Patent number: 4652545
    Abstract: Catalysts for hydroconversion of heavy oils, particularly those containing Ramsbottom carbon precursors, comprise nickel or cobalt and molybdenum on porous alumina containing 1-3% silica. The catalysts have total pore volume of 0.5 to 1.5 ml/gm with at least 70% of the pore volume in pores of 40-60.ANG. pore radius and with only about 10-35% of the nickel or cobalt in acid extractable form.
    Type: Grant
    Filed: May 6, 1985
    Date of Patent: March 24, 1987
    Assignee: American Cyanamid Company
    Inventors: John F. Lindsley, Marvin S. Goldstein, William H. Quayle
  • Hydrotreating catalyst
    Patent number: 4465790
    Abstract: Improved hydrodenitrogenation catalysts comprise catalytic metals, e.g. molybdenum and nickel, on supports of co-precipitated alumina and titania with more than 5% of the catalyst weight consisting of titanium oxide in the support.
