Abstract
A facilitated transport membrane with improved permeance and selectivity to alkene-based unsaturated hydrocarbons is provided. The facilitated transport membrane includes a solid state polymer electrolyte and additionally a non-volatile surfactant that enhances long-term operation stability. In preparing the facilitated transport membrane for separation of alkenes, a porous supporting membrane is coated with a solid polymer electrolyte layer having a non-volatile polymer, a non-volatile surfactant, and a salt of a transition metal capable of complexing selectively and reversibly with alkenes.
Claims13
A facilitated transport membrane for separation of alkene-based hydrocarbons, comprising:
- a polymer electrolyte layer comprising a salt of a transition metal selectively and reversibly reactive to an alkene, a non-volatile polymer, and a surfactant for maintaining the activity of the transition metal, the polymer electrolyte layer being in a solid state at an operating temperature and a porous supporting membrane.
