In response to global efforts combat climate change, many research have contributed upgrading cryogenic distillation, an energy-intensive petrochemical operation, especially for olefin/paraffin separation. Metal-organic framework (MOF) membranes can be a competitive candidate this purpose. work, we reviewed the main progress of MOF separations, with focus on potential ZIF-8 C 3 H 6 /C 8 Membran...
