Effect of Carbonization Conditions on Gas Permeation of Methyl Imide Based Carbon Molecular Sieve Hollow Fiber Membranes
(Received October 3, 2013, Revised October 7, 2013, Accepted October 9, 2013)
Abstract
In the present study, carbon molecular sieve (CMS) hollow fiber membranes were prepared by carbonizing amethyl imide hollow fiber precursor, which was spun by non-solvent induced phase separation process. And effects of carbonizationparameters such as pre-oxidation, pyrolysis, and post-oxidation on the gas permeation were systematicallyinvestigated. CMS membrane having the highest gas flux was obtained by carbonizing the precursor through a combinedprocess of air pre-oxidation at 250°C for 2h, nitrogen pyrolysis at 550°C for 2h, and oxygen post-oxidation at 250°C for 2h.The optimized membrane showed a considerable gas permeance : the H2, He, CO2 permeances were 69.72, 35.61, 31.01GPU, respectively, and the O2 and N2 permeances were ignorable. Therefore, it was clear that the prepared CMS hollow fibermembrane was a promising membrane for recovering small gases such as hydrogen and hellium and carbon dioxide.
