“The results of the regeneration experiment are shown in Figure 5. For both TSA-N2-stripping and VTSA regeneration methods, desorption efficiency increases with the increasing temperature. Desorption attains 100% efficiency when temperature reaches 328 K for TSA-N2-stripping and 348 K at 20 KPa for VTSA. Full regeneration temperatures of different MOFs are presented in Table 3. The milder desorption temperature, corresponding to the low enthalpy of CO2 adsorption of MIL-101(Cr)16, suggests that the regenerative heat can come from the waste heat of the power plant, thus enhance the economic feasibility of the process.”
