Abstract
One of the potential candidates to produce biogas is food waste. The main composition in biogas are methane which has calorific value and carbon dioxide which has no calorific value. To increase calorific value of biogas, a purification process needed by removing carbon dioxide content. In this study, coconut shell charcoal is applied as activated carbon. The different flow rates of biogas entered into adsorption column are investigated. It was found that the optimum flow rate is 2 Liter/minute to increase methane from 90.20 to 98.14%.
