An efficientwayof removingthe amountofC02 from the environment is vital to help reduce the greenhouse affecting the world today. In order to do that, several techniques has been developed such as Pressure Swing Adsorption and Temperature Swing Adsorption. This project is conducted based on the Electrical Swing Adsorption technique. The effect of electrical potential applied to the C02 adsorption and desorption processis observed and studied. The main objective of the project is to study the effect of various application of electrical potential to the adsorption and desorption process. It is done on a bench scale experiment. Some studies have been done obtainan in-depth knowledge on how the electrical supplied actually affect the adsorption and desorption process. Some recommendations have been made to further improve the experimental setup. Throughout the studies, the experiment is conducted using any available equipment prepared by the lab in order to have a necessary gas flow loop and a complete electrical circuit within the experimental setup. Some improvement has been done from the previous setup. However it is more towards the safety of the user to avoid electrical shock. The experiment is conducted using \.5 mm Granular Activated Carbon (GAC). During the adsorption process using C02 and desorption process using N2 and He gas, the gasflow is maintained at approximately 20 kPa. The voltage is varied from 2 - 10V during adsorption and 0.2 - 1 V during desorption. The result showed that, at an increasing voltage applied the amount adsorbed decreased. Increasedvoltage reducedthe adsorption rate while supporting the desorptionrate.
