Evaluation of high‐performance adsorbents for separation of CO 2 from industrial effluent gases

The aim of this work is the investigation of several CO 2 adsorbents such as three synthetic zeolites (4A, 5A, and 13X), a natural zeolite (clinoptilolite), an activated carbon (AC), and a metal organic framework (MOF‐MIL‐53) for the postcombustion CO 2 capture via temperature‐pressure swing adsorption. The adsorbents were evaluated in terms of the CO 2 adsorption capacity and performance during successive adsorption–desorption cycles at different conditions (1–6 bar and 120–180°C) using different mixtures of gases simulating a combustion process stream (N 2 /CO 2 /O 2 /CO). The 13X zeolite showed excellent adsorption capacity of 4.3 mmolCO 2 /g zeolite and very stable performance during successive cycles. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
