CO2 capture by liquid amine has many drawbacks. These processes require significant energy to regenerate the solvents, releasing the captured CO2 for storage or utilization, which leads to increased operational costs and can diminish the overall efficiency of carbon capture systems. Recent research explores new promising techniques by CO2 capture using highly efficient solid sorbents. This study then focuses on enhancing a porous alumina material with potassium carbonate (K2CO3) and monoethanolamine to optimize CO2 capture capacity and regeneration performance.
