CO₂ gas separation using mixed matrix membranes based on polyethersulfone/MIL-100(Al)

Abstract The excessive use of natural gas and other fossil fuels by the industrial sector leads to production great quantities pollutants, including CO 2 , SO NO x . Consequently, these gases increase temperature earth, producing global warming. Different strategies have been developed help overcome this problem, utilization separation membrane technology. Mixed matrix membranes (MMMs) are hybrid that combine an organic polymer as a inorganic compound filler. In study, MMMs were prepared based on polyethersulfone (PES) type metal–organic framework (MOF), Materials Institute Lavoisier (MIL)-100(Al) [Al 3 O(H O) (OH)(BTC) ] (BTC: benzene 1,3,5-tricarboxylate) using phase inversion method. influence properties produced addition 5, 10, 20, 30% MIL-100(Al) (w/w) PES was also investigated. Fourier-transform infrared spectroscopy (FTIR) analysis indicated no chemical interactions occurred between MIL-100(Al). Scanning electron microscope (SEM) images showed agglomeration at PES/MIL-100(Al) thickness dense layer increased up 3.70 µm. After (w/w), permeability for O N enhanced approximately 16, 26, 14 times, respectively, compared with neat membrane. thermal stability membranes, reaching 40°C thermogravimetry (TGA). An 20% selectivity /O from 2.67 4.49 (approximately 68.5%), 10% /N 1.01 2.12 110.1%).
