Abstract：

The　separation　of　aromatic/aliphatic　hydrocarbon　mixtures　is　crucial　in　the　petrochemical　industry.　Pervaporation　is　regarded　as　a　promising　approach　for　the　separation　of　aromatic　compounds　from　alkanes.　Developing　membrane　materials　with　efficient　separation　performance　is　still　the　main　task　since　the　membrane　should　provide　chemical　stability,　high　permeation　flux,　and　selectivity.　In　this　study,　the　hyperbranched　polymer　(HBP)　was　deposited　on　the　outer　surface　of　a　polyvinylidene　fluoride　(PVDF)　hollow-fiber　ultrafiltration　membrane　by　a　facile　dip-coating　method.　The　dip-coating　rate,　HBP　concentration,　and　thermal　cross-linking　temperature　were　regulated　to　optimize　the　membrane　structure.　The　obtained　HBP/PVDF　hollow-fiber-composite　membrane　had　a　good　separation　performance　for　aromatic/aliphatic　hydrocarbon　mixtures.　For　the　50%/50%　(mass)　toluene/n-heptane　mixture,　the　permeation　flux　of　optimized　composite　membranes　could　reach　1766　g·m−2·h−1,　with　a　separation　factor　of　4.1　at　60　°C.　Therefore,　the　HBP/PVDF　hollow-fiber-composite　membrane　has　great　application　prospects　in　the　pervaporation　separation　of　aromatic/aliphatic　hydrocarbon　mixtures.　©　2024　The　Chemical　Industry　and　Engineering　Society　of　China,　and　Chemical　Industry　Press　Co.,　Ltd
