THE FACILITATED OLEFIN TRANSPORTING COMPOSITE MEMBRANE COMPRISING NANOSIZED SILVER OXIDE OR COPPER OXIDE, AND IONIC LIQUID

摘要

PURPOSE: A facilitated olefin transporting composite membrane is provided to separate materials such as propane, propylene etc, and to facilitate transferring of silver oxide nanoparticles or copper nanoparticles by a carrier. CONSTITUTION: A facilitated olefin transporting composite membrane includes a porous support and a gas separating layer. The gas separating layer is formed by casting nanoparticles, cupric oxide nanoparticles and ionic liquid on the porous support. The porous support is one or more selected form a metal support, a polymer support, and a ceramic support. The polymer support is polysulfone or polyester porous support. The ionic liquid is BMIM^+BF4^-(1-butyl-3-methylimidazoliumtetrafluoroborate) or BMIM^+PF6^-(1-butyl-3-methylimidazolium hexafluorophosphate).
