Isoprene/n-pentane separation using sulfonated ionomer membranes containing SPEEK-AgNO3 |
| 초록 |
The separation of olefin from hydrocarbon mixtures is an important part of petrochemical industry. Since conventional cryogenic distillation processes for the separation of olefin/paraffin are energy-intensive, an alternative energy saving process is requiring. Among a number of alternative technologies, separation using facilitated transport membrane with metal ion such as Cu+ or Ag+ was attracted much interest because of its low energy consumption process. Sulfonated ionomer membranes, sulfonated poly(ether ether)ketone (SPEEK)-AgNO3, were prepared and tested for separation of the isoprene/n-pentane mixtures. The performances of the membranes were significantly affected by the degree of sulfonation (DS) of PEEK. The selectivity over n-pentane increased with the increasing DS of PEEK. |
