Aj. Vanzyl et Vm. Linkov, INFLUENCE OF OXYGEN-CONTAINING HYDROCARBONS ON THE SEPARATION OF OLEFIN PARAFFIN MIXTURES USING FACILITATED TRANSPORT/, Journal of membrane science, 133(1), 1997, pp. 15-26
Perfluorosulfonated ionomer (PSI) membranes were used to investigate t
he separation of olefin/paraffin mixtures by means of silver-based fac
ilitated transport of olefins. Pentene and pentane were used as model
compounds and separation factors as high as 33 were obtained. Influenc
e of linear C-3-C-6 alcohols and ketones on the separation of the pent
ene/pentane mixtures was investigated. The presence of oxygenates incr
eases the fluxes of olefins and paraffins, resulting in lower selectiv
ity for hydrocarbon separation.
