  • RHO zeolites and method of making the same
    Patent number: 10654024
    Abstract: Disclosed are novel, as-crystallized RHO zeolite compositions with improved uniformity in morphology. These RHO compositions are useful for preparing cation-exchanged RHO zeolites that can be used as adsorbents for oxygen and/or nitrogen with improved properties. The adsorbents can be used in pressure swing adsorption processes for selectively adsorbing oxygen and/or nitrogen from feed streams such as an air stream or crude argon stream. Also disclosed are novel methods of preparing RHO zeolites with improved morphology control.
    Type: Grant
    Filed: September 28, 2018
    Date of Patent: May 19, 2020
    Assignee: Air Products and Chemicals, Inc.
    Inventors: Elizabeth M. Seibel, William Jack Casteel, Jr., Garret Chi-Ho Lau, Roger Dean Whitley
