CO₂ Adsorption on Zeolites and Fe-MOF for Carbon Capture and Storage (CCS)

Abstract

This research focused on the development of suitable materials for capturing and storing CO₂ (CCS). Ferum-metal organic framework (Fe-MOF) and zeolite were prepared as adsorbents for the CO₂ adsorption process. These adsorbents were characterised by employing X-ray diffraction (XRD) and Fourier Transform Infrared (FTIR) analysers. The adsorptive capacity of CO₂ was conducted in an assembled facility containing of a metallic tubular container set up with a pure CO₂ gas stream from a cylinder-shaped tank. The performance of these two adsorbents was investigated using two different parameters which are operating pressure and dosage of adsorbents. The exit concentration of CO₂ was analyzed periodically using gas chromatography. Based on the FTIR and XRD studies, the findings suggest that the zeolite and Fe-MOF were successfully formed. The optimal adsorption conditions obtained for both adsorbents were 0.3 g of adsorbent dose and 1 bar of operating pressure. In conclusion, zeolite exhibits better performance as a CO₂ adsorber due to its higher adsorption capacity than Fe-MOF.
