(122c) Process-Based Adsorbent Screening and Design for Post-Combustion CO2 Capture By Vacuum Swing Adsorption

Over the past 20 years, adsorption based post-combustion CO2 capture has attracted keen interests from both process engineers and material scientists. The traditional approach to process development involves synthesis of adsorbents; screening using metrics such as selectivity etc.; perform lab-scale breakthrough experiments; computer-based optimization and scale-up the separation. Very often, materials that are touted to be promising do not show success at a process-scale. This is primarily because the complexities of the process are not considered in screening materials.

This talk will summarize the outcome of activities in our research groups that have focused on understanding the importance of material properties that lead to the desired outcomes of post-combustion CO2 capture, i.e., achieving product purity and recovery, while minimizing parasitic energy and maximizing productivity. These studies provide insight into what properties should be targeted in material synthesis to make them successful at a process level.
