(211e) Engineering tools for screening and discovery of solid sorbents for CO2 capture

The past two years have seen major advances in adsorption technology for CO2 capture. Particularly, metal-organic frameworks (MOFs), traditionally considered exotic sorbents, have now been deployed for large-scale post-combustion CO2 capture from industrial flue gas. This has created a renewed interest in screening adsorbents for CO2 capture applications. Over the years, our work in this area has motivated us to develop both computational and experimental methods that allow for the meaningful screening of materials. In this talk, we will summarize recent developments in process modelling and optimization accelerated by machine learning that can be used to screen adsorbents rapidly. Further, we discuss the experimental evaluation of competitive isotherms for complex systems, e.g., CO2+H2O that have important consequences on the practical deployment of the sorbent. We will pay particular attention to breakthrough/ frontal-analysis experiments, an area where Prof. Andreas Seidel-Morgenstern has made major contributions.
