Strategic Fast Induction Heating to Combat Hysteresis Barriers in a Flexible MOF for Rapid CO2Desorption in Biogas Upgrading

Abstract

AbstractA major challenge in Cyclic Swing Separation using flexible adsorbents that have high equilibrium CO2 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 CO2at 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 CO2desorption from flexible adsorbents at a moderately elevated temperature (70 °C).
