“…For example, polyethersulphone support hollow fiber membrane was coated with sulphonated poly(ether ether ketone) (SPEEK) and applied for nanofiltration [18], flue gas dehydration and gas separation [24] whereas a polypropylene fiber coated with SPEEK was applied as a membrane contactor for olefin/paraffin separation [12] and polysulphone hollow fiber membrane coated with layer of SPEEK was used to stabilize a liquid membrane for metal ion transport [25]. Polyelectrolyte was also used for a bilayer membrane for fuel cell applications [23] by casting a layer of SPEEK solution on a polyimide membrane.…”

We have investigated and established a preparative method of using a solid-phase extraction cartridge containing Ag + -exchange resin (Ag + -SPE) for separating olefins and paraffins in the saturate fractions of coal tar and petroleum coker oil. The successful separation of paraffins and olefins was confirmed by gas chromatography coupled with mass spectrometry (GC− MS). Proton nuclear magnetic resonance ( 1 H NMR) spectroscopy was applied to determine the olefin structures for olefin-type distributions. None or negligible amounts of iso-α-olefins were detected by 1 H NMR in the coal tar but were found significant in the coker oil. Gas chromatography coupled field ionization time-of-flight mass spectrometry (GC−FI-TOF MS) was employed to determine the molecular distribution of paraffins and olefins. With separate paraffin and olefin fractions, the differentiation between isomers, such as monocycloparaffins versus monoolefins, can be made.
