Parallel passage contactor and method of adsorptive gas separation

An adsorptive gas separator for adsorptive gas separation of at least a first component from a multi-component fluid stream comprising:

• a plurality of adsorbent structures, said adsorbent structures further comprising:
• a first adsorbent layer having a first permeability value along a z-axis of said first adsorbent layer and a first adsorbent material further comprising:
• a first composition, and
• a first pore size;
• a second adsorbent layer, different than the first adsorbent layer, having a second permeability value along a z-axis of said second adsorbent layer and a second adsorbent material further comprising:
• a second composition, and
• a second pore size;
• wherein at least one of:
• said first permeability value and said second permeability value differ;
• said first composition and said second composition differ;
• said first pore size and said second pore size differ;
• and
• said first adsorbent material having a greater hydrophobicity relative to said second adsorbent material;
• a barrier layer interposed between said first adsorbent layer and said second adsorbent layer;
• a first fluid passage where at least a portion of said first fluid passage is defined by said first adsorbent layer;
• and
• a second fluid passage, fluidly separate from the first fluid passage, where at least a portion of said second fluid passage is defined by said second adsorbent layer, and
• a structure for sealing at least a portion of said first fluid passage, and at least a portion of said second fluid passage,
• wherein said first fluid passage and said second fluid passage are fluidly separate within said adsorptive gas separator.
