High performance ceramic hollow fiber supported PDMS composite pervaporation membrane for bio-butanol recovery
In this work, ceramic hollow fiber supported polydimethylsiloxane (PDMS) composite membranes were developed by dip-coating PDMS layer on the surface of macroporous ceramic hollow fiber support. By controlling the properties of polymer solution and ceramic hollow fiber, high-quality ceramic hollow fiber supported PDMS composite membranes were fabricated for pervaporation (PV) recovery of biobuta...
متن کاملCorrelated Effect of Air Gap and PVP Concentration on the Structure and Performance of PVDF Ultrafiltration Hollow Fiber Membrane
Polyvinylidene fluoride/polyvinylpyrrolidone (PVDF/PVP) hollow fiber membranes were fabricated by dry-jet wet-spinning process. The correlated effects of the air gap length and PVP concentration ((1) the air gap length effect at the low and high PVP concentration in the dope solutions, as well as (2) the effect of the PVP concentration at the same air gap length) on the cross-section structure ...
متن کاملMultichannel Mixed-Conducting Hollow Fiber Membranes for Oxygen Separation
A multichannel mixed-conducting hollow fiber (MMCHF) membrane, 0.5 wt % Nb2O5-doped SrCo0.8 Fe0.2O3-d (SCFNb), has been successfully prepared by phase inversion and sintering technique. The crystalline structure, morphology, sintering behavior, breaking load, and oxygen permeability of the MMCHF membrane were studied systematically. The MMCHF membrane with porous-dense asymmetrical microstructu...
متن کاملCO2-tolerant mixed-conducting multichannel hollow fiber membrane for efficient oxygen separation
A mixed-conducting multichannel hollow fiber membrane (MCMHF) based on CO2-tolerant SrFe0.8Nb0.2O3–δ (SFN) oxide has been successfully prepared by phase inversion and sintering technique. The morphology, breaking load, oxygen permeability under CO2 atmosphere, thermal cycling performance and the long-term stability of the membrane were investigated in detail. The prepared membrane has a signifi...
متن کاملSeparation of Carboxylic Acids from Aqueous Solutions using Hollow Fiber Membrane Contactors
Separation of formic, acetic, and propionic acids from the aqueous stream using membrane solvent extraction has been studied using three different membrane contactors made of polysulfone (PS), polyethersulfone (PES), and polyvinylidene fluoride (PVDF) using two different solvents; including ethyl acetate (EA) and diisopropyl ether (DIPE). The efciency of the membrane and e...
