  • Method for densely packing molecular sieve adsorbent beds in a PSA system
    Patent number: 4931071
    Abstract: The improvement in the separation of gaseous mixtures by pressure swing adsorption (PSA) is disclosed. The interparticle voids in kinetically-selective PSA adsorbent beds are filled with fine particles of kinetically-selective adsorbent. The ratio of the average diameter of the coarse adsorbent particles to the average diameter of the fine particles, the size of the fine particles themselves and the percent of volume of the fine particles in the bed are all critical to optimum PSA performance.
    Type: Grant
    Filed: March 9, 1989
    Date of Patent: June 5, 1990
    Assignee: The BOC Group, Inc.
    Inventors: Robert H. Kaplan, Alberto LaCava, Arthur I. Shirley, Steven M. Ringo
  • Method for densely packing molecular sieve adsorbent beds in a PSA system
    Patent number: 4853004
    Abstract: The improvement in the separation of a gaseous mixtures by pressure swing adsorption (PSA) is disclosed. The interparticle voids in conventional PSA adsorbent beds are filled with fine particles. The ratio of the smallest dimension of the coarse adsorbent particles to the largest dimension of the fine particles, the size of the fine particles themselves and the present of volume of the fine particles in the bed are all critical to optimum PSA performance. The fine particles may be comminuted adsorbent or an inert material, i.e. one having no adsorptive capacity.
