| 英文摘要 | cellulose hollow fiber membranes (chfm) were prepared using a spinning solution containing n-methylmorpholine-n-oxide as solvent and water as a nonsolvent additive. 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 desiccation. the gas permeation properties of co2, n-2, ch4, and h-2 through chfm were investigated as a function of membrane water content and operation pressure. the water content of chfm had crucial influence 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 significant effect on n-2, h-2, and ch4. at the end of this article a detailed comparison of gas permeation performance and mechanism between the chfm and cellulose acetate flat membrane was given.
