摘要: Using a wet sipinning process, cellulose hollow fiber membranes were prepared from a dope composed of cellulose/N-methylmorpholine-N-oxide/water system. Water was also used as both the internal and external coagulant. It was demonstrated that the phase separation mechanism of this system was delayed demixing. The CHFM was revealed to be homogeneously dense structure after naturally drying. The gas permeation properties of CO2, N2, CH4, and H2 through CHFM were investigated as a function of membrane water content and operation pressure. The water content of CHFM had crucial in.uence on gas permeation performance, and the permeation rates of all gases increased sharply with the increase of membrane water content. The permeation rate of CO2 increased with the increase of operation pressure, which has no signicant effect on N2, H2, and CH4. At 25°C and 0.5 MPa, when the water content of CHFM was increased to its saturation value (about 80%), (P/l)CO2 reached a maximum value of 75E-8 cm3(STP)/(cm2 s cmHg), with ideal separation factors of 45 for N2, 30 over CH4, and 16 over H2. In conclusion, the CHFM prepared has a promising application potential in the field of CO2 removing and recycling.
