  • Removal of impurities from hydrogen-containing materials
    Patent number: 8535423
    Abstract: Methods of purifying hydrogen-containing materials are described. The methods may include the steps of providing a purifier material comprising silica. The silica may be heated at temperature of about 100° C. or more in a dry atmosphere to form activated silica. The activated silica may be contacted with a starting hydrogen-containing material, where the activated silica reduces a concentration of one or more impurity from the starting hydrogen-containing material to form the purified hydrogen-containing material, and where the activated silica does not decompose the purified hydrogen-containing material.
    Type: Grant
    Filed: August 30, 2012
    Date of Patent: September 17, 2013
    Assignee: Matheson Tri-Gas, Inc.
    Inventors: Tadaharu Watanabe, Mark Raynor, Ade Lau, Hirotaka Mangyo
