主 题:hybrid membranes hierarchical porous SBA-15 sieving effect pervaporation desulfurization
摘 要:The utilization of materials with a hierarchical porous structure as multi-functional additives is highly attractive in the preparation of hybrid *** this study,novel hybrid membranes are designed by embed-ding hierarchical porous Santa Barbara Amorphous 15(SBA-15)with a dual-pore architecture(micropores and mesopores)for pervaporation *** SBA-15 with cylindrical mesopores provides molecular transport expressways to ensure improved permeability,while micropores on the wall have molecular sieving effects that are essential for the enhancement of permselectivity of thiophene *** thiophene/n-octane mixture as a model system,the hybrid membrane with embedded 6 wt-%SBA-15 exhibits optimal pervaporation desulfurization performance with a permeation flux of 22.07 kg·m^-2·h^-1 and an enrichment factor of ***,the detailed structure and properties of hybrid membranes are systematically *** study demonstrates the immense potential of hierarchical porous materials as additives in membranes to simultaneously increase permeability and permselectivity.
