Mixed matrix membrane technology: enhancing gas separations with polymer/molecular sieve composites
There is increased interest in membranes with high selectivity and productivity for a number of gas separations of interest to the petroleum and chemical industries. While glassy, polymeric membranes have provided efficient performance to date, getting significant improvements over current technology will likely require novel materials. This has led researchers to study molecular sieve membranes, including carbon molecular sieve and zeolitic materials. While these membranes offer very attractive properties, their cost, difficulty of commercial scale manufacture and brittleness remain major challenges. This paper will review the development and status of a new technology based on composite membranes of polymer matrices in which molecular sieves are dispersed to give enhanced separation properties compared to membranes of the polymer alone, with results reported for the separation of CO2 from natural gas.
