Patent number: 8535423Abstract: 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: GrantFiled: August 30, 2012Date of Patent: September 17, 2013Assignee: Matheson Tri-Gas, Inc.Inventors: Tadaharu Watanabe, Mark Raynor, Ade Lau, Hirotaka Mangyo

Patent number: 7033418Abstract: A process for removing trace amounts of moisture and/or one or more impurities from contaminated hydride, inert and non-reactive gases, thus decreasing the concentration of the impurities to parts-per-billion (ppb) or parts-per-trillion (ppt) levels. The gas purifier materials of this invention include thermally activated aluminas, said aluminas including organic alumina materials, modified organic alumina materials, and modified inorganic aluminas. The thermally activated alumina materials of this invention are activated by heating the alumina material at a temperature between about 50° C.–1000° C. in an inert or non-inert atmosphere or in a vacuum and maintaining the activated material in the inert or non-inert atmosphere or in a vacuum atmosphere subsequent to said activation but prior to use.Type: GrantFiled: September 27, 2002Date of Patent: April 25, 2006Assignee: Matheson Tri-Gas, Inc.Inventors: Tadaharu Watanabe, Dan Fraenkel
