Title: Effective separation of propylene/propane binary mixtures by ZIF-8 membranes
Abstract: The separation of propylene/propane mixtures is one of the most important but challenging processes in the petrochemical industry. A novel zeolitic imidazole framework (ZIF-8) membrane prepared by a facile hydrothermal seeded growth method showed excellent separation performances for a wide range of propylene/propane mixtures. The membrane showed a permeability of propylene up to 200 barrers and a propylene to propane separation factor up to 50 at optimal separation conditions, well surpassing the “upper-bound trade-off” lines of existing polymer and carbon membranes. The experimental data also showed that the membranes had excellent reproducibility, long-term stability and thermal stability.
