Abstract
Biogas is an alternative energy that can be a substitute solution for energy fuel that is cheap and environmentally friendly. The composition of biogas is CH4, CO2, N2, H2, O2, and H2S. CH4 gas is the main element in biogas which has a high heating value. In addition to CH4 gas which is very much needed, there are also CO2 contents which actually disturb or damage. If this element is present in biogas, it will disrupt the combustion process itself. Therefore, efforts are needed to reduce CO2 levels which are expected to increase the quality of biogas. The study was conducted to reduce levels of CO2 in biogas by using coconut shell ash adsorbent. The method used in this study is pure research that is by taking into account the variation in the flow rate of biogas (2, 4, 6, 8 and 10 lt / min) that passes through the adsorbent. Furthermore, purified biogas was obtained as many as 5 variations of biogas (AB2, AB4, AB6, AB8 and AB10). The research was continued by testing purified biogas in the performance of combustion engines with variations in engine speed 1500, 2500, 3500 and 4500 rpm. Purified biogas with various variations shows a significant effect on engine torque. While all variations of engine speed show an increase in torque. Biogas obtained from the purification process shows that the greater the rate of biogas purification, the greater the torque produced. So if the torque of an engine increases in magnitude, it will indirectly be followed by the effective power that occurs will increase as well.
