  • Use of lithium-containing fau in air separation processes including water and/or carbon dioxide removal
    Patent number: 6824590
    Abstract: A process for separating a feed gas into at least one product gas includes: (a) providing a gas separation apparatus with at least one adsorption layer including a lithium-exchanged FAU adsorbent having water desorption characteristics, defined by drying curves, similar to those for the corresponding fully sodium-exchanged FAU, a heat of adsorption for carbon dioxide equal to or lower than that for the corresponding fully sodium-exchanged FAU at high loadings of carbon dioxide, and onto which the adsorption layer water and/or carbon dioxide adsorb; (b) feeding into the gas separation apparatus a feed gas including nitrogen, oxygen, and at least one of water and carbon dioxide; and (c) collecting from a product end of the gas separation apparatus at least one product gas containing oxygen.
    Type: Grant
    Filed: January 13, 2003
    Date of Patent: November 30, 2004
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Douglas Paul Dee, Robert Ling Chiang, Gregory John Gondecki, Roger Dean Whitley, Jane Elizabeth Ostroski

  • ARGON/OXYGEN SELECTIVE X-ZEOLITE
    Publication number: 20020108495
    Abstract: An AgX-type zeolite having a silver exchange level of 20-70% and a Ar/O2 Henry's law selectivity ratio at 23° C. of 1.05 or greater has an optimum combination of selectivity for argon over oxygen at lower cost than higher silver exchange levels. This material can be used in oxygen VSA/PSA processes to produce oxygen at purities above 97%.
