Abstract
The embodiments of the disclosure relate generally to adsorbent beds, adsorbent contactors, and methods of using same. The disclosure includes polymer filaments that include an adsorbent particle, such as a zeolite, metal oxide, metal organic framework. A plurality of fibers composed of the polymer filaments can be formed into an adsorbent bed for use in pressure swing and/or temperature swing adsorption processes. The plurality of fibers can be packed into a bed randomly, spirally wound, or woven into a fabric that can be formed into a contacting structure. The adsorbent particle can be contained within the polymer filament and can interact with a medium having a component for adsorption by being in fluid communication with the medium via tortuous pathways within the polymer.
