  • Cracking hydrocarbons over laminar heavy metal aluminosilicates
    Patent number: 4033858
    Abstract: Hydrocarbons are catalytically cracked using a catalyst made from Laminar 2 : 1 layer-lattice aluminosilicate minerals containing intra-lattice multivalent ions such as nickel, copper, cobalt. Procedures for preparing the inventive minerals are given.
    Type: Grant
    Filed: June 17, 1976
    Date of Patent: July 5, 1977
    Assignee: NL Industries, Inc.
    Inventor: William T. Granquist
  • Laminar heavy metal aluminosilicates
    Patent number: 3976744
    Abstract: Laminar 2 : 1 layer-lattice aluminosilicate minerals containing intra-lattice multivalent ions such as nickel, copper, cobalt and others. The minerals are particularly useful in catalytic operations. Procedures for preparing the inventive minerals are given.
    Type: Grant
