| Abstract: | Perfluorosulfonated ionomer (PSI) membranes were used to investigate the separation of olefin/paraffin mixtures by means of silver-based facilitated transport of olefins. Pentene and pentane were used as model compounds and separation factors as high as 33 were obtained. Influence of linear C3C6 alcohols and ketones on the separation of the pentene/pentane mixtures was investigated. The presence of oxygenates increases the fluxes of olefins and paraffins, resulting in lower selectivity for hydrocarbon separation. |
