Effect of nano Zinc Oxide on gas permeation through mixed matrix poly (Amide-6-b-Ethylene Oxide)-based membranes
Poly (amide-6-b-ethylene oxide)/Zinc Oxide (PEBA/ZnO) mixed matrix membranes were fabricated using ethanol/water as solvent by solvent casting method. The concentration of ZnO in membrane was set to 0.1 wt.% and the synthesized membranes were characterized by AFM and FTIR. Effects of ZnO nanoparticle on CO2, CH4 and N2 permeabilities, and CO2/N2<...

متن کاملGas Permeation Modeling through a Multilayer Hollow Fiber Composite Membrane
In this study, a time-dependent 2D axisymmetric model of a multilayer hollow fiber composite membrane for gas separation is proposed. In spite of the common multilayer membranes, which a dense layer coated on a porous support layer and subjected into the feed stream, here, the porous support is exposed to the feed gas. In this regard, the governing equations of species transport are developed f...
متن کاملOxygen Diffusion in Oxide Crystals - Tracing New Routes to Identify the Rate Limiting Step of Oxygen Permeation through Perovskite Membranes
Perovskites are known as mixed electric conductors because they show both electronic (via electron holes) and ionic (via oxygen vacancies) conductivity. Since the electron conductivity is orders of magnitude higher than the ionic one, oxygen vacancy bulk diffusion is regarded as the rate limiting step in oxygen permeation through perovskites. However, for thin perovskite layer the rate of this ...
