Abstract
Adsorbent material for use in pressure swing adsorption (PSA) related processing can provide improved purification processing with reduced temperature differentials between adsorption and desorption processing of the bed of adsorbent material. Embodiments can be configured so that adsorbent material has occluded micropores or macropores. The occlusion of the micropores or macropores can be up to 42% of the micropores the adsorbent material in some embodiments. At least one metal acetate can be utilized for the occlusion of the micropores or macropores. Utilization of the adsorbent material having occluded micropores or macropores was surprisingly found to increase the yield for purification of a product gas in spite of the occlusion of the micropores or macropores.
