  • Oxygen scavenging metal-loaded high surface area particulate compositions
    Patent number: 6284153
    Abstract: An oxygen scavenging composition composed of a carrier and a metal coated, inert, porous particulate material having the metal substantially in a zero valence state. The composition is contained within the interior cavity of a container to scavenge oxygen therein. The composition may form at least a part of the interior surface of the container or be present therein in the form of a film, mat, sachet or ceramic.
    Type: Grant
    Filed: August 19, 1999
    Date of Patent: September 4, 2001
    Assignee: W.R. Grace & Co.-Conn
    Inventors: James George Miller, Thomas Andrew Blinka, Drew Ve Speer, William Alfred Feehley, Jr.
  • Oxygen scavenging metal-loaded ion-exchange composition
    Patent number: 6086786
    Abstract: An oxygen scavenging composition composed of a carrier material and a metal-loaded cationic exchange material having the metal in a zero valence state. The composition is contained within the interior cavity of a container to scavenge oxygen therein. The composition may form at least a part of the interior surface of the container or be present therein in the form of a film, mat, sachet or ceramic.
    Type: Grant
    Filed: June 21, 1999
    Date of Patent: July 11, 2000
    Assignee: W. R. Grace & Co. -Conn.
