摘要: Abstract By mixing functionalized carbon nanofibers as inorganic substances with polysulfone (PSF) membrane, an extraordinary ability to separate CO 2 from CH 4 well N O was developed in this study. The series of amine-functionalized-CNFs (F-CNFs)/PSf mixed matrix membrane various F-CNFs contents (0–1.5 wt.%) prepared by solution casting method. In paper, characterizations such as; morphology and crystalline structure have been conducted details investigate the structures properties membranes. effects F-CNF loading on gas separation (O , ) performance MMMs were evaluated using laboratory-scale apparatus. exhibited higher permeability perm-selectivity /CH due interaction amine groups compared neat PSf membrane. permeation measurement showed about 3.57 1.58 (GPU), /N selectivity 7.7, 3.5, respectively, obtained for MMM 0.5 wt.% loading. As a result, membranes can be efficient separating . increased addition solution, then decreased
