A major challenge in Cyclic Swing Separation using flexible adsorbents that have high equilibrium CO 2 adsorption capacity is their very low-pressure hysteresis that hinders efficient desorption. Mg-Gallate MOF is such a flexible adsorbent that only begins to release CO 2 at its pore closing pressure at 0.08 bar and 30 °C, showing very slow and inefficient desorption in pressure or temperature swing. Therefore, a novel strategy is presented that combines state of art technique Magnetic Induction Heating with a vacuum swing for fast and efficient CO 2 desorption from flexible adsorbents at a moderately elevated temperature (70 °C).
Mg-Gallate metal-organic framework (MOF) has large hysteresis in its CO 2 desorption isotherm, hindering efficient regeneration in adsorption swing processes. Utilizing combined induction heating and vacuum desorption under mild, energy-efficient conditions boost regeneration performance. A hybrid ferromagnetic Mg-Gallate extrudate material gets heated up rapidly via magnetic induction and swiftly releases adsorbed CO 2 molecules.
