An efficient temperature swing adsorption (TSA) process for separating CO2 from CO2/N2 mixture using Mg-MOF-74

The regeneration (heating and cooling) time has been tuned to explore the performance improvement for the TSA process. The TSA optimal key performance indices in terms of CO2 purity, recovery, productivity, and process power consumption have been found to be 96.22%, 86.5%, 0.279 kg of CO2 per hour per kg of Mg-MOF-74, and 663.8 kWh per ton of CO2 captured, respectively. These productivity and power consumption values showed a substantial enhancement in the CO2 adsorption separation compared to those reported in the literature, especially when the heating process is used for the desorption part of the process.
