Post-combustion CO2 capture using nontoxic iron-based amino-MIL-101 (Fe)

Amino-MIL-101(Fe) was synthesized and assessed for post-combustion CO2 capture. A hybrid model has been applied which resulted in better agreement with the experimental data. The achieved adsorption values for the pure CO2 and N2 gases at 1 bar and 298 K were equal to 0.41 and 0.33 mmol.g (1). The kinetic modeling of adsorption data indicated that the adsorption of CO2 and N2 at low pressure was not kinetically controlled. The adsorption selectivity of CO2 over N2 was estimated using IAST, which was achieved equal to 1.6.

Automated summary

Amino-MIL-101(Fe) was synthesized and tested for post-combustion CO2 capture, with a hybrid model providing better agreement with experimental data. The adsorption process of CO2 and N2 at low pressure was found to not be kinetically controlled. The adsorption selectivity of CO2 over N2 was estimated to be 1.6 using IAST.
