Abstract

Developing carbon capture and storage (CCS) technology is a promising route to tackle the rising level of atmospheric carbon dioxide (CO2). Capturing CO2 at high temperature by solid sorbents is attractive in both pre-combustion and post-combustion scenarios. This paper highlights the importance of CO2 sorption kinetics and reviews the published research available on the calcium-based sorbents, magnesium-based sorbents, layered double hydroxide sorbents and alkali ceramic-based sorbents. Insights are provided into the main factors affecting the CO2 sorption kinetics such as reaction and mass transfer mechanism, material microstructures and reaction operating conditions. Finally, a few possible research gaps are identified and recommendations for future research are proposed.
