Separation of light olefin and paraffin element is one of the most crucial issuses in petrochemical industry due to its profitable potential as precursor of petrochemical products, but facing technical predicament from similar physicochemical properties of two components. Membrane technology is considered as a good alternative for current cryogenic separation, however, current olefin/paraffin separation membranes are suffered from generally low permeability and selectivity, as well as its durability problem. Here, we have synthesized mixed matrix composite membrane using polyimide-based ZIF-8/graphene oxide 2-D nanocomposite, presenting high propylene/ propane separation performance and long-term stability.
