Title: Separation of CO{sub 2} from CO{sub 2}/N{sub 2} mixture using supported polymeric liquid membranes at elevated temperatures

Abstract

Novel supported polymeric liquid (SPL) membranes have been prepared and shown to be applicable for the separation of CO{sub 2} from mixtures with N{sub 2} at the elevated temperature encountered in flue gas. The membranes were fabricated by immobilizing polystyrene, polyethylene, and polydimethylsiloxane into the pores of borosilicate glass supports. At 250 C, the CO{sub 2} permeability and CO{sub 2}/N{sub 2} separation factors were 3000--9000 barrer and 1.7--3.7, respectively. It was shown that polymers which have a lower T{sub g} or melting temperature than the operating temperature can be used as SPL membrane materials at elevated temperatures.
