Coal bottom ash is a promising sorbent for the capture of carbon dioxide as it contains alkaline-Earth metal oxide such as calcium oxide and magnesium oxide. Coal bottom ash is one of the byproduct generated by in coal power plant which currently facing a problem with disposal and lack of usage. The scope of this study is to deepen the understanding of the behavior of coal bottom ash as CO2 sorbent when subjected to different parameters. In this work, coal bottom ash sorbents are being studied for its ability to capture CO2 at a different operating temperature and also at different concentration of CO2. The coal bottom ash sample that is used for this work is obtained from Manjung Coal Power Plant in Perak. The study is divided into two parts, which are characterization study and thermogravimetric analysis study. For the first part of the study, the sample is analysed by using XRD, XRF, and SEM. As for the second part of the experiment, the sample will go through carbonation/decarbonation cycle using TGA. The result from the characterization shows that CBA has 20.6% of CaO and a mere 2.6% of MgO and other various metal oxides. The crystalline structure from XRD proves that it has a slighltly similar structure to pure CaO within the sample. The TGA analysis shows that the highest uptake capacity is at 600 oC – 700oC which valued at 37.85% of adsorption percentage and as it goes to 800oC the uptake capacity decreases.
