Facilitated transport membranes for separation of isoprene/n-pentane |
| 초록 |
The facilitated transport membranes containing sulfonated poly(ether ether)ketone (SPEEK)-AgNO3 layers on top of a hydrophilic support were prepared and tested for separation of the isoprene/n-pentane mixtures. The SPEEK-AgNO3 membranes showed good selectivity for isoprene over n-pentane and long-term stability. The degree of sulfonation (DS) of SPEEK was measured by 1H NMR spectroscopy. The performances of the SPEEK-AgNO3 membranes were significantly affected by DS of SPEEK. The selectivity for isoprene over n-pentane increased with the increasing DS of SPEEK. In a liquid-liquid membrane contactor system using a hollow fiber membrane module, it was found that the performance of the membrane modules was influenced by the concentration and the flow rate of aqueous Ag solution used as an absorption solution and the flow rate of isoprene/n-pentane mixtures. |
