John S. Magee, Jr. has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Pillared interlayered clay products
    Patent number: 4271043
    Abstract: Pillared interlayered clays are reacted with a base such as ammonium hydroxide to increase the ion exchange capacity thereof. The pillared interlayered clays are prepared by reacting a smectite clay, such as bentonite, with a metal complex polymer, such as chlorhydrol, and calcining the resulting product.
    Type: Grant
    Filed: October 1, 1979
    Date of Patent: June 2, 1981
    Assignee: W. R. Grace & Co.
    Inventors: David E. W. Vaughan, Roger J. Lussier, John S. Magee, Jr.
  • Stabilized pillared interlayered clays
    Patent number: 4248739
    Abstract: Stable pillared interlayered clays are prepared by reacting smectite clays with high molecular weight cationic metal complexes of metals such as aluminum and zirconium. The high molecular weight complexes are prepared by hydrolysis of copolymerization of a metal complex such as aluminum chlorohydrol. The pillared, interlayered clays possess a high degree of thermal and hydrothermal stability and may be used in the preparation of catalysts and sorbents.
    Type: Grant
    Filed: September 4, 1979
    Date of Patent: February 3, 1981
    Assignee: W. R. Grace & Co.
    Inventors: David E. W. Vaughan, Roger J. Lussier, John S. Magee, Jr.
  • Silica-alumina hydrogel catalyst
    Patent number: 4226743
    Abstract: A dense, attrition resistant catalyst is prepared by precipitating a silica alumina hydrogel at high pH, and subsequently reacting the alkaline hydrogel with sufficient acid aluminum salt at a pH below 4 to obtain an acidic hydrogel slurry. The slurry is then processed into a catalyst by spray drying, washing and ion exchanging. The catalyst may include substantial quantities of clay and/or crystalline aluminosilicate zeolites.

  • Pillared interlayered clay materials useful as catalysts and sorbents
    Patent number: 4176090
    Abstract: Stable pillared interlayered clay compositions are prepared by reacting smectite type clays with polymeric cationic hydroxy metal complexes of metals such as aluminum, zirconium, and/or titanium. These novel interlayered clay compositions which possess substantial surface area in pores of less than 30 A in diameter are used as catalysts, catalytic supports, and sorbents.
