ETS-10 titanosilicate materials selectively adsorb carbon dioxide from gaseous mixtures containing carbon dioxide and light paraffins such as methane and ethane.

Removal of carbon dioxide from paraffins

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 Baand Ba/Hprovided 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.
