“Durable cyclic adsorption/regeneration behavior of sorbents is essential for long-term operation. Figure 6 depicts the CO2 adsorption of MIL-101(Cr) during repetitive cycles (5 cycles) in the presence of moisture (RH 10%), SO2 (100 ppm) and NO (100 ppm) at 298 K, with regenerations under flowing N2 at a temperature of 328 K and pressure of 20 KPa at 348 K for 10 min. The cyclical data reveal that the adsorption performance of MIL-101(Cr) is fairly stable, with <5% drop in CO2 adsorption capacity after 5 adsorption/regeneration cycles.”
