| Abstract: | The PDMS/PVDF composite hollow fiber membrane for the separation of n-hexane/nitrogen was prepared.The effect of feed pressure,concentration,flow rate,permeation pressure and temperature on the performances of composite membrane,were also studied.The results show that the permeation rate of n-hexane was 1.4E-07 mol/（m2·s ·Pa）,the separation factor was about 90 when the conditions in operating were given. |
