The Pervaporation Performance of Polyimide-Block-Polyethylene Glycol Membranes for Gasoline Desulphurization: Effect of PEG Groups

Abstract:

Polyimide-block-polyethylene glycol (PI-b-PEG) copolymers were synthesized and membranes were prepared for sulfur removing from model gasoline by pervaporation. The result of the pervaporation performance using the polyimide (PI) membrane and the PI-b-PEG membranes showed that the polyethylene glycol (PEG) groups were effective to increase the permeation flux with less decreasing of sulfur enrichment factor. And the permeation flux was increased by the increasing of weight content and the decreasing molecular weight of PEG groups. The copolymerization of PI with PEG is an effective method to enlarge the permeation flux of the PI membranes.
