Abstract: The main objective of this work is to compare and model sorption isotherms of pure carbon dioxide to well characterised activated carbon pellets (ACP) prepared at different pyrolysis temperatures to determine the most appropriate sample for CO2 storage. CO2 adsorption on the activated carbon samples were studied using a manometric adsorption method. Experiments were conducted at room temperature and in the pressure range between 1 and 23 bars. The surface area, pore volume and pore diameter were evaluated from the analysis of N2 adsorption isotherm data. The characterisation of carbon materials was performed by scanning electron microscopy (SEM). The results reveal that all the samples are essentially microporous and have a high CO2 adsorption capacity. The highest CO2 adsorption value is 9.52 mmol/g at room temperature and 23 bars. The experimental results were fitted using Toth's approach and with corrected Langmuir's equation. Modelling provides affinity settings of carbon dioxide for different activated carbon.
