  • Porous solid amine adsorbents and applications
    Patent number: 12447434
    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.
