Abstract

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.
