(144h) A Process Engineer's Perspective of Screening Adsorbents for CO2 Capture

In the last 20 years, significant efforts have been invested in developing adsorption processes for CO₂ capture. The explosion in adsorbent synthesis and molecular simulations has generated hundreds of thousands of (hypothetical & real) adsorbents, e.g., Metal-Organic Frameworks (MOFs). This excitement has led to an implicit assumption that the key bottleneck in developing large-scale adsorption processes is discovering the right adsorbent. The reality, however, is that perhaps one MOF [1] has moved from the lab to the industrial scale. This two-part talk will be based: on 1. How process engineering allows us to "meaningfully" screen sorbents [2]., and\, 2. Perspectives and challenges associated with the computational screening of materials for CO2 capture sorbents [1,3]. Both parts are heavily influenced by the pioneering works of Doug Ruthven in the fields of process engineering and sorbent characterization.
