Abstract: The present invention relates to a pressure-temperature swing adsorption process wherein gaseous components that have been adsorbed can be recovered from the adsorbent bed at elevated pressures. In particular, the present invention relates to a pressure-temperature swing adsorption process for the separation of C2+ hydrocarbons (hydrocarbons with at least 2 carbon atoms) from natural gas streams to obtain a high purity methane product stream. In more preferred embodiments of the present processes, the processes may be used to obtain multiple, high purity hydrocarbon product streams from natural gas stream feeds resulting in a chromatographic-like fractionation with recovery of high purity individual gaseous component streams.

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.
