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.
