Abstract: A reinforced porous adsorbent fiber includes a reinforcing thread partially or completely embedded in a fiber adsorbent component, the latter including an active adsorbent such as a polyamine, an inorganic particulate adsorbent or an amine-modified inorganic particulate adsorbent, dispersed in a porous polymeric matrix. In specific examples, the thread-reinforced adsorbent fibers have attractive CO2 adsorption/desorption performance, good tensile mechanical strength and/or flexibility.

Abstract: Porous solid amine adsorbents are prepared by bringing into contact a first (e.g., dope) solution, including a water insoluble polymer and a water-soluble amine polymer, with an aqueous solution containing a multifunctional chemical agent. The first solution can be obtained by dissolving the water insoluble polymer and the water-soluble amine polymer in a polar solvent. The adsorbents can be in the form of beads, sheets, fibers, hollow fibers, etc. and can be used in the removal of acid gases, CO2, for instance, from fluid streams.

Abstract: An adsorbent device includes adsorbent fibers laid along or wound around a center tube. In a specific example, the adsorbent fibers are porous solid amine adsorbent fibers. A module for purifying a raw fluid includes one or more adsorbent devices that can be installed in a vessel in series or in parallel. The module can be configured for axial or cross flow operation and can be employed to purify a gas containing a contaminant such as an acid gas. In some implementations, the module is provided with one or more heating elements that can be used to release adsorbed contaminant to regenerate the adsorbent fibers.
