Summary:

Carbon capture using ionic liquids (ILs) as absorbents represents a transformative approach toward sustainable decarbonization. Unlike traditional aqueous amines, IL-based absorption offers superior thermal stability, negligible volatility, and customizable affinity for CO2, making it a focal point of next-generation CCUS research.
This session focuses on the latest breakthroughs in ionic liquid absorption technologies. We welcome contributions addressing both fundamental and applied aspects, including:
(1) Molecular engineering of ILs, deep eutectic solvents and porous ILs to enhance CO2 solubility and selectivity.
(2) Interfacial phenomena, mass transfer enhancement, and kinetic studies of CO2 absorption in ILs.
(3) Novel absorber/stripper designs, hybrid separation processes (IL absorption coupled with membranes or adsorption), and energy penalty reduction.
(4) Life-cycle assessment, cost evaluation, and scalability studies of IL-based absorption processes.
(5) Pilot tests, industrial case studies, and real-world performance evaluation of IL-based capture units.
This session will facilitate in-depth discussions on overcoming bottlenecks in cost and scalability, paving the way for the next generation of carbon capture solvents.
