Abstract

Biogas is increasingly viewed as an encouraging kind of renewable energy capable of replacing a portion of fossil fuels. As a result, the overall objective of this thesis is to investigate the efficiency of biogas purification using activated carbon (AC) micro discs to remove carbon dioxide (CO2). It is also crucial to explore the influence of different AC to bentonite clay (BC) ratios on the CO2 adsorption capacity of the AC micro disc. The AC produced from coconut shell is combined with the six designed AC to BC ratios with the same amount of methyl cellulose (MC) and polyvinyl alcohol (PVA) to form into micro discs. The AC micro discs' CO2 adsorption capacity is tested by inserting them into a quartz tube and releasing CO2 into the tube to examine the ppm reading projected by a gas analyser. This experiment design is then statistically validated using one-way ANOVA to discover the most optimum ratio for achieving a good shape of the AC micro disc while avoiding interference with AC's natural CO2 adsorption capabilities. According to the findings, Ratio 4, which consists of 80% AC, 15% BC, 3.5% MC, and 1.5% PVA that forms a 20g weighted AC micro disc, is the optimal ratio for maintaining the shape of the micro disc without compromising the rate of CO2 adsorption capability. This thesis concluded that there is significant variation in the CO2 adsorption capability of different AC to BC ratios of micro discs.
