抄録

Novel carbon hollow fiber membranes were successfully fabricated using poly(phenylene oxide) (PPO) and its functionalized derivatives as a polymeric precursor. These carbon membranes had properties above the upper bound of conventional polymeric membranes reported by Robeson including PPO polymeric precursors. Metal containing carbon membranes derived from sulfonated PPO (SPPO) were prepared by ion exchange method and the effect of metal cations on the gas transport properties was studied. We found that the incorporation of transition metal ions such as Ag+ significantly enhanced gas permeabilities without affecting the ideal selectivities. We also found that a simple modification of the PPO precursor with a TMS group enhanced gas permeabilities of carbon membrane. It can be considered that the incorporation of silica-like species into the carbon membranes was formed and it increased the apparent free volume of the carbon matrix. The development of flexible carbon hollow fiber membranes was successfully achieved using SPPO as a precursor polymer. The superior flexibility combined with excellent gas separation performance were obtained when pyrolyzed at 600 °C. This result presents a promising possibility for the advancement of commercial application of carbon membranes. Selective membrane separation of saturated water vapor from olefin gas such as ethylene and propylene has been investigated using two types of membrane modules based on SPPO carbon hollow fibers.
