Carbon dioxide adsorption and desorption study using bimetallic calcium oxide impregnated on iron (III) oxide
Bimetal adsorbent system of calcium oxide impregnated on iron (III) oxide were evaluated as a potential source of basic sites for CO capture. The adsorbents were prepared by impregnation method were calcined at 200 until 600 °C. Several characterizations were carried out using XRD, BET and CO -TP...

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