Alternatives to amine-based capture & new technologies

Abstract

Large improvements in separations technology will require novel materials with enhanced properties and performance. The fundamental interlinks for success in merging synthesis and process incorporation are the structure, relevant physical/chemical properties, and performance of new materials. Specific materials with these interlinks are room-temperature ionic liquids (RTILs) and their polymers and composites. As a chemical platform, RTILs have an enormous range of structural variation that can provide the ability to "tune" their properties and morphology for a given application. Introduction of chemical specificity into the structure of RTIL-based materials is an additional key component. Membrane separation is the focus as a process for implementation. There have not been new materials successfully developed for this process in thirty years. For CO 2 capture, the target improvement in productivity is two orders of magnitude or more compared to commercial materials currently available.
