Separation of isoprene-pentane mixtures using facilitated transport membranes

摘要

The facilitated transport membranes, Sulfonated Poly(Ether Ether)Ketone (SPEEK)-AgNO3, were prepared and tested for separation of the isoprene-pentane mixtures. The SPEEK-AgNO3 membranes showed good selectivity for isoprene over n-pentane and long-term stability. In the liquid-liquid membrane contactor system using a hollow fiber membrane module, it was found that the performance of the membrane was influenced by the concentration and the flow rate of Ag solution.
