  • SOLID-STATE COPPER(I) SORBENTS FOR OLEFIN SEPARATIONS
    Publication number: 20240367089
    Abstract: Disclosed herein is a process for separating a hydrocarbon feed gas mixture comprising constituents including ethylene to produce a separated ethylene product. The disclosed process employs a solid-state ethylene sorbent and temperature and/or pressure swing adsorption and membrane separation and demonstrates a methodology to reduce the net heat of reaction during the adsorption of ethylene onto an adsorbent.
    Type: Application
    Filed: July 17, 2024
    Publication date: November 7, 2024
    Inventors: Rasika DIAS, Naleen B. JAYARATNA, Richard D. NOBLE, Matthew G. COWAN, Devaborniny PARASAR

  • Selective adsorption of gaseous alkenes into non-porous copper(I) complexes: controlling heat of adsorption and loading pressure
    Patent number: 11517877
    Abstract: Disclosed are air-stable small-molecule adsorbents trimeric [Cu—Br]3 and [Cu—H]3 that undergo a reversible solid-state molecular rearrangements to [Cu—Br.(alkene)]2 and [Cu—H.(alkene)]2 dimers. The reversible solid-state rearrangement allows one to break adsorbent design trade-offs and achieve low heat of adsorption while retaining high selectivity and uptake.
