  • Patent number: 5670125
    Abstract: A gas mixture comprised of nitric oxide and, optionally an inert gas, and containing small amounts of nitrogen dioxide, and perhaps moisture and sulfur dioxide, is purified by passing the gas stream through a bed of zeolite having a silica to alumina ratio not greater than about 200. The concentration of nitrogen dioxide, sulfur dioxide and moisture in the gas stream are reduced to about 1 ppm or less as the gas mixture passes through the bed of zeolite.
    Type: Grant
    Filed: September 25, 1995
    Date of Patent: September 23, 1997
    Assignee: The BOC Group, Inc.
    Inventors: Lien-Lung Sheu, Ramakrishnan Ramachandran, Theodore R. Galica
  • Patent number: 5514204
    Abstract: A gas mixture comprised of nitric oxide and, optionally an inert gas, and containing small amounts of nitrogen dioxide, and perhaps moisture and sulfur dioxide, is purified by passing the gas stream through a bed of metal cation-free silica, alumina, or zeolite. The concentration of nitrogen dioxide, sulfur dioxide and moisture in the gas stream are significantly reduced as the gas mixture passes through the bed of adsorbent.
    Type: Grant
    Filed: July 7, 1994
    Date of Patent: May 7, 1996
    Assignee: The BOC Group, Inc.
    Inventors: Lien-Lung Sheu, Ramakrishnan Ramachandran, Theodore R. Galica
  • Patent number: 5417742
    Abstract: Perfluorocarbons are recovered from gas streams by subjecting the gas stream to an adsorption process in a bed of one or more energetically homogeneous adsorbents such as silicon-rich adsorbents of the FAU structure, silicon-rich adsorbents of the BEA structure, silicon-rich adsorbents of the MOR structure. The adsorption process is preferably pressure swing adsorption or temperature swing adsorption.
