Design of Molecular Sieve Membranes

Molecular sieve membranes have created interest as high-performance separation systems for production of petro-based and renewable fuels and chemicals. Compared to thermodynamically driven separation methods such as distillation, membrane-based processes can substantially reduce the energy and capital costs of separating molecules on a large scale. This is attractive because separations account for 40% of the total energy consumption in the chemical industry. Separation based on the preferential adsorption and molecular sieving mechanisms can make the large-scale industrial deployment of membranes possible. Our research has been devoted to fabricate nanometer thin, pin-hole/crack free membranes on porous supports. In this talk, I will highlight what we learned regarding three high performance nanoporous materials; nanometer-thick 2D zeolites, metal organic framework (ZIFs), organosilica and their use in designing homogeneous, highly selective/permeable thin membranes will be addressed.
