  • Modified ETS-10 zeolites for olefin separation
    Patent number: 8017825
    Abstract: An as prepared Na-ETS-10 zeolite was modified by ion exchange with a mono-, di-, or tri-valent cation and mixtures thereof. Several of the modified ETS-10 zeolites showed improved pressure swing capacity during the selective adsorption of ethylene from an ethylene/ethane mixture, relative to Na-ETS-10, although the selectivity of adsorption decreased. Modification with Ba2+ and Ba2+/H+ provided modified ETS-10 zeolite adsorbents having a good balance of selectivity and pressure swing capacity for the separation of ethylene/ethane mixtures, making them useful adsorbents for PSA processes.
    Type: Grant

    Date of Patent: September 13, 2011
    Assignee: The Governors of the University of Alberta

Several of the modified ETS-10 zeolites showed improved pressure swing capacity during the selective adsorption of ethylene from an ethylene/ethane mixture, relative to Na-ETS-1 0, although the selectivity of adsorption decreased. Modification with Ba2+ and Ba2+/H+ provided modified ETS-10 zeolite adsorbents having a good balance of selectivity and pressure swing capacity for the separation of ethylene/ethane mixtures, making them useful adsorbents for PSA processes.
