Abstract

Bimetal adsorbent system of calcium oxide impregnated on iron (III) oxide were evaluated as a potential source of basic sites for CO2 capture. The adsorbents were prepared by impregnation method were calcined at 200 until 600 °C. Several characterizations were carried out using XRD, BET and CO2-TPD analysis. The CaO loading increased the basicity of the adsorbent significantly enhance the CO2 chemisorption. Furthermore, it drastically reduced the desorption temperature to 310-490 °C, which is important in chemisorption aspect. The CaO/Fe2O3200 which calcined at 200 °C was found to be most efficient. The CO2 chemisorption (81.29 mg CO2/g adsorbent) was contributed most compared to physisorption (4.64 mg CO2/g adsorbent).
