(732l) Separation of H2 Using Fluorinated Polymer Membranes RAPID Project 6.9

Membrane technology for the separation of H2 is a widely sought-after technology. Developing high performance, economically feasible polymeric membranes for this gas separation is of major interest to the H2 purification industry. The use of fluoropolymers for H2 separation provides the opportunity to achieve a high selectivity separation while maintaining high flux. RAPID Project 6.9 is investigating the use of perfluoro(butenyl vinyl ether) and perfluoro(2,2-dimethyl-1,3-dioxole) for the separation of H2 from N2 and CO2. Experimental permeability measurements have been obtained using the pressure-rise method. Molecular simulation and structural predictive models are being utilized to provide insight on synthesis and understanding fundamental solubility and diffusivity behavior of gases in fluorinated polymers. Promising materials are being developed into hollow-fiber membranes in order to measure mixed gas selectivity and throughput to meet the industrial challenge of this separation.
