Abstract
Biogas is a flammable gas produced from the fermentation process of organic materials by anaerobic bacteria. The principle of making biogas is the decomposition of organic materials anaerobically (closed from free air) to produce gas, the majority of which is methane gas (CH4) and carbon dioxide (CO2). The anaerobic decomposition process is assisted by a number of microorganisms, especially methane-producing bacteria. This process will produce biogas purification as an alternative energy that can reduce the use of fossil fuels. This research aims to produce a prototype design for CO2 gas adsorption in a series of biogas reactors with a 3-stage system, obtain optimal flow rates in reducing CO2 levels and find out which is the most effective commercial activated carbon in level 1, level 2 and level filter housings. 3 in reducing CO2 levels. In this research, the design was made in a simple, systematic and efficient manner. The design was made using solid software. In the design, modifications were made, first the vacuum pump and flow meter were placed in the reactor and a blockage occurred by sludge and the stirrer hitting the pump during the stirring process. Then modifications were made, namely that the pump and flow meter were placed next to the reactor and given a stand, only the front of the pump entered the reactor to suck up the gas and then flowed to the level 1 filter housing. With this tool, the biogas was adsorbed using activated carbon. Commercial size 100 mesh is 65 grams. The results of the absorption process with a flow rate of 2 L/minute at level 2 were able to reduce CO2 levels by 96% and the most effective in reducing CO2 levels was at level 3 by 92%.
