“The effects of adsorption temperature on MIL-101(Cr) were evaluated by analyzing breakthrough curves at different temperatures, as shown in Figure 2. The breakthrough time was found to decrease with increasing temperature. The adsorption capacity of MIL-101(Cr) at various temperatures is given in Figure 3. The adsorption capacity of MIL-101(Cr) decreases with increasing temperature from 0.495 mmol/g at 298 K to 0.279 mmol/g at 348 K. Capacity decreases sharply from 298 K to 318 K but more gradually from 318 K to 348 K. This adsorption behavior is typical of physical adsorption, which was verified by FT-IR. Note that after CO2 adsorption there were no obvious shifts in the locations of the bands. The discrepancy between the two CO2 capacities for MIL-101(Cr) given in Table 1 can be explained by the lower gas flow rate employed in this work.”
