  • Polymers containing ionic groups for gas separation and storage
    Publication number: 20070119302
    Abstract: Polymeric materials containing ionic groups, which can be used as membranes and sorbents for separating gas components, for example, separating CO2 from flue gas streams and from natural gas streams, and sorbents for storing gas components. Such separation materials are used for pre-combustion separations, post-combustion separations, and natural gas separations, and are alternatives to the conventional amine absorption process.
