Abstract

This study investigates the effectiveness of treating biogas with 20% calcium hydroxide solution to improve its quality and energy content. The treatment process significantly increased methane content from 64.0% to 98.1% and reduced impurities like CO2, H2S, CO, and water vapor. Treated biogas demonstrated a 35% faster heating time compared to raw biogas and outperformed kerosene, showcasing its potential as a more efficient and cleaner-burning fuel source. The results highlight the benefits of biogas treatment, making it a viable alternative energy source for cooking, heating, and other applications. This research contributes to the development of sustainable energy solutions, emphasizing the importance of biogas treatment for improved energy efficiency and reduced environmental impact.
