Abstract: Functionalized polymer compositions are provided that can have beneficial properties for CO2 sorption and/or desorption. The functionalized polymer compositions can be based on polymers of intrinsic microporosity. The polymers of intrinsic microporosity can then be at least partially reacted to form polymers functionalized with guanidine and/or amidine derivatives where at least a portion of the polymeric repeat units have a substituent that includes a guanidine derivative and/or amidine derivative as a functional group. Optionally, the functionalized polymers of intrinsic microporosity can be further reacted in order to further modify the guanidine derivative and/or amidine derivative that is substituted at one or more locations of a polymeric repeat unit.

Abstract: Systems and methods are provided for operating a combined cycle power plant while enhancing the CO2 content of the flue gas generated by the power plant. The CO2 content is enhanced by using a combination of exhaust gas recycle and oxygen-enriched combustion. The oxygen-containing flow for performing the oxygen-enriched combustion can be generated by an integrated pressure swing adsorption process that allows for production of a commercial grade nitrogen stream (95 vol % or more of N2) while also providing an oxygen-containing stream with an oxygen content between 25 vol % and 48 vol % with high 02 recovery.
