CO2 removal can be conducted via adsorption process. This project concentrate on the effect of electrical field on CO2 adsorption and desorption process using fixed bed at different voltage. The main objective of this project is to study the effect of different voltages towards the adsorption and desorption process using a bench scale experiment setup. Literature study on the effect of polarizability of CO2 and activated carbon towards the adsorption and desorption process was done. Further improvement on the existing bench scale experiment setup and experimental method has also been made. The scope of study shall be conducting the bench scale experiment and literature review on the microscopic view (i.e polarizability) of the electrical enhanced adsorption and desorption. This includes improvement of the method and setup of the existing lab apparatus. The experiments conductedfor the adsorption/ desorption processwere using 2.5 mm and 1.5 mm size granular activated carbon (GAC). The experiment was also done under a 20 kPa CO2 and N2 flow for all the experiment. The results shows that variation in voltage affects the maximum uptake, rate of adsorption and rate of desorption of the fixed bed activated carbon. As voltage increased, the maximum uptake of CO2 gas in activated carbon andthe rate of adsorption decreased, but the rate of desorption increased. For all three observed factors, the graph trend of 2.5 mm size GAC shows a higher value than the 1.5 mm GAC.
