Inorganic Adsorbent Membranes for Methane Separation from Carbon Dioxide

The possibility of improving both the selectivity and the flux for gas separation applications with inorganic adsorbent membranes has been looked at for separation of CO2, CH4, H2, N2 and other gases by synthesizing crystalline zeolites on top and in the pores of different inorganic support materials. Preliminary results are very promising, with observed separation factors much higher than membranes alone or adsorbents alone.
