As part of DOE’s Carbon Capture Simulation Intuitive (CCSI), which my current work centers around. These involve solid-sorbent adsorption models that include moving bed and bubbling fluidized bed reactors with temperature swing regeneration, moving bed solid-heat exchanger models, CO2 compression models, and the integration of all these sub-models in a complete CO2 capture and compression post-combustion process.
