A bstract : Two types of mixed matrix membranes were developed by UOP in the late 1980s. The first type includes adsorbent polymers, such as silicalite‐cellulose acetate (CA), NaX‐CA, and AgX‐CA mixed matrix membranes. The silicalite‐CA has a CO 2 /H 2 selectivity of 5.15 ± 2.2. In contrast, the CA membrane has a CO 2 /H 2 selectivity of 0.77 ± 0.06. The second type of mixed matrix membrane is PEG‐silicone rubber. The PEG‐silicone rubber mixed matrix membrane has high selectivity for polar gases, such as SO 2 , NH 3 , and H 2 S.
