Title: Thin film composite membranes for separation of alkenes from alkanes

Patent ·
OSTI ID:1576382
; ; ;

Composite membranes comprised of at least two layers, one of the layers being a silver ionomer and a second layer which is a fluorinated polymer with certain permeability properties, are especially useful for the separation of alkanes from alkenes, Particularly useful is a three-layer composite membrane in which a porous layer is laminated to the second layer.
