Abstract
Biogas is a renewable energy source produced through anaerobic fermentation; however, its quality is often limited by the presence of carbon dioxide (CO2) and other impurities. High CO2 content results in a lower heating value, necessitating a purification process. This study aims to improve biogas quality through the adsorption method using activated carbon as an adsorbent, while determining the effects of gas flow rate and adsorbent bed height on purification effectiveness. The research utilized a fixed-bed adsorption column with biogas flow rate variations of 150, 200, 250, 300, and 350 ml/min, and adsorbent height variations of 4, 8, 12, 16, and 20 cm. The biogas composition before and after purification was analyzed using Gas Chromatography (GC) to monitor changes in CH4 and CO2 levels.The results demonstrate that activated carbon is effective in reducing CO2 levels and increasing CH4 content. Lower gas flow rates and higher adsorbent columns resulted in greater adsorption efficiency due to increased contact time between the gas and the adsorbent. Specifically, the activated carbon achieved CO2 adsorption rates ranging from 10.93% to 96.65%, leading to an increase in CH4 content by 8.66% to 78%. Optimal adsorption was achieved at an adsorbent height of 20 cm and a flow rate of 200 ml/min, yielding a final composition of 98.5070% CH4 and 1.4930% CO2. These results successfully meet the Indonesian National Standard (SNI) for biogas quality, which requires a minimum CH4 content of 80% and a maximum CO2 content of 18%.
