Abstract:
A membrane composition and process for its formation are disclosed from the removal of carbon dioxide (CO2) from mixed gases, such as flue gases of energy production facilities. The membrane includes a substrate layer comprising inorganic oxides, a barrier layer of in-situ formed Li2ZrO3, a Li2ZrO3 sorbent layer and an inorganic oxide cap layer. The membrane has a feed side for introduction of mixed gases containing nitrogen (N2) and a sweep side for recovery of CO2 wherein the membrane has a relatively high selectivity for CO2 transport at temperatures in the range of 400° to 700° C.
