Enhancing MISA CO2 capture via dual-functional materials and thermal management

This dissertation addresses CO₂ capture through Temperature Swing Adsorption (TSA) and its electrified alternative, Magnetic Induction Swing Adsorption (MISA), focusing on energy optimization via advanced heating and cooling strategies. The experimental study evaluated various dual-functional sorbent configurations, including core-shell (CS-DFM) and homogeneous (H-DFM-1 and H-DFM-2) materials, assessing adsorption capacity, working capacity, energy consumption, and desorption profiles. Results indicate that integrated architectures provide higher CO₂ uptake, faster desorption, and more efficient energy utilization compared to physical mixtures. The implementation of the Heat Impulse strategy further enhanced adsorption and working capacities while reducing energy consumption during regeneration. Preliminary integration of Phase Change Materials (PCM) significantly improved the cooling phase, decreasing the time required to return the system to ambient conditions and enabling faster cyclic operation. Nevertheless, PCM requires optimization to withstand prolonged thermal exposure, and numerical simulations remain preliminary, based on simplified models. Overall, the findings highlight the potential of advanced thermal strategies and integrated material architectures to improve the efficiency of electrified adsorption processes, providing guidance for future studies and operational optimization.
