This study is to fabricate a hollow fiber gas separator system to reduce the CO2 concentration indoors. In this study, a CO2 gas separation system is setup base on the membrane separation via the surface modification of commercial polysulfone (PSF) porous membranes to produce a gas selective layer. Dip coating method is applied to modify the surface of hollow fiber membrane with rich of hydroxyl and amine functional groups to enhance the CO2 gas absorption. Dip coat aqueous solution consists of polyvinyl-alcohol (PVA) and surface been amine modified meso-porous material SBA-15-NH2. The modified membranes were characterized by SEM and XPS analysis. The gas separation results show that at lower input gas pressure, CO2 gas has larger gas permeability (GP) value than nitrogen at room temperature. When applying the dip coat condition of 0.5 wt% PVA and 0.1wt% SBA-15-NH2, the GP values are 1.1 and 0.2 (×10-3, cm3/s.cm2.cm-Hg) for CO2 and nitrogen at gas pressure of 3.75 cmHg respectively and the CO2/N2 gas selectivity ratio is 5.6. 張淑美 2014 學位論文 ; thesis 63 zh-TW |
