Adsorption of CO₂ on Activated Carbon, Fe‐Based Metal Organic Framework, ZnO, and CaO for Carbon Capture and Storage Application

Abstract

Activated carbon (AC) from coconut shell, iron‐based metal organic framework (Fe‐MOF), zinc oxide (ZnO), and calcium oxide (CaO) were prepared as adsorbents for the CO2 adsorption process. The adsorption experiments were performed in a self‐designed fixed‐bed small reactor to study the influence of reaction conditions on the CO2 adsorption capacity of adsorbents. According to the findings, Fe‐MOF showed better performance in CO2 adsorption compared to the other selected adsorbents. The results were supported by the high surface area of Fe‐MOF, which was greater than that of AC, ZnO, and CaO. The optimal parameters for CO2 adsorption of all adsorbents were determined in terms of adsorbent dosage, operating pressure, and CO2 adsorption time.

CO2 and CO Capture on the ZnO Surface: A GCMC and Electronic Structure Study

“…CO 2 capture/storage is a challenge for global warming, where several studies have been addressed for the adsorption of CO 2 . − Studies of CO 2 capture show a maximum amount of CO 2 adsorbed ranging from approximately 25–176.66 mg/g at higher pressure. , …”
