英文摘要	The urgent challenge of climate change, primarily driven by global warming and carbon dioxide (CO2) emission, necessitates innovative solutions for carbon capture. CO2 capture by liquid amine has many drawbacks. These processes require significant energy to regenerate the solvents, releasing the captured CO2 for storage or utili-zation, 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 mon-oethanolamine (MEA) to optimize CO2 capture capacity and regeneration performance. The developed sorbent was conducted in a fluidized bed reactor, showcasing its effectiveness in capturing CO2 from air. This adsorbent can be reused by applying with microwave radiation for sorbent regeneration, a cutting-edge approach that allows precise temperature control and reduces regeneration time. The electrical microwave power, regeneration time and %closing regeneration time were study variables in sorbent regeneration process. By harnessing mi-crowave, this method not only improves efficiency but also enhances the sorbent's reusability. This innovative technique presents a significant step forward in advancing cost-effective and energy-efficient CO2 capture technologies, crucial for mitigating the impact of climate chang
