Adsorption breakthrough and cycling stability of carbon dioxide separation from CO2/N2/H2O mixture under ambient conditions using 13X and Mg-MOF-74

Cycling stability over more than 90 cycles is also simulated; and shows that, a dehydration process is recommended to be carried out before the CO2 separation process for efficient energy consumption and sustainable adsorbents. The total recyclable amounts of adsorbed CO2 are about 0.94 and 3.07 mmol/g for 13X and Mg-MOF-74, respectively, under 101.3 kPa adsorption, 2 kPa desorption, 86% relative humidity, and 298 K. The cyclic CO2 separation is found to be a robust method more than the breakthrough separation to evaluate the real adsorption capacities.
