Formatted abstract
CO2 problem is a threat to human beings and this must be controlled. Therefore, this thesis is trying to address the issue of CO2 emission damaging the atmosphere, through the development of CO2 capture technologies. Electrical swing adsorption is a promising technology for CO2 capture, which can reduce the cost up to 50% from the conventional technologies. The principle of electrical swing adsorption is to adsorb CO2 and desorbs CO2 by applying a low voltage across the adsorbent.

The objective of this thesis is to test the concept of electrical swing adsorption. A small scale of electrical swing adsorption system was developed, which consists of adsorption cell, carbon-based material, DC power supply, CO2 analyzer, gas supply system, temperature meter and pressure meter.

The adsorption cell was designed in a way, which includes a spring to permit the ability for testing difference lengths of adsorbents. Adsorbents were fabricated based on the ratio of activated carbon and phenolic resin. A process of drying, carbonization using N2 and activation using CO2 were needed to finalize the adsorbent in order to carry out the experiment. An investigation was done on adsorption and desorption in the two experiments. With the results obtained from the two experiments, the adsorption and desorption can be achieved in this developed system by using the concept of electrical swing adsorption.
