Utilizing Raman and IR spectroscopies to investigate supported Na2O/Al2O3 and K2CO3-promoted hydrotalcite for reversible CO2 capture

摘要

An emerging area of research utilizing reversible CO2 chemisorbents is sorption enhanced reactions (SER). The SER concept is based on circumventing the thermodynamic limitations (purity and conversion) of an equilibrium-controlled reaction by selectively removing a reaction product with the use of a sorbent, thereby increasing the conversion and rate of the forward reaction. A brief review of this concept may be found elsewhere.
