Open the CIPO recordAbstract From the Canadian patent
The improvement in the separation of 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 percent 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.
