Abstract

Biogas is produced from the anaerobic digestion of biodegradable organic matter. However, its application is limited because it contains impurities such as carbon dioxide (CO2) in high concentrations. Therefore, it is necessary to remove CO2 to improve the energy content of biogas. Porous adsorbents such as activated carbon have been widely used to remove CO2 from biogas. However, the performance of the split is limited, so the addition of active sites is required. In this research, chitosan impregnated porous carbon was used for biogas purification. Modification of porous carbon was made by impregnating chitosan on activated carbon with a ratio of chitosan to activated carbon of 0:1, 0.1:1, and 0.3:1. The success of the impregnation process of chitosan into activated carbon was analyzed from the results of characterization using Fourier Transform Infrared Spectroscopy (FTIR) and Scanning Electron Microscopy (SEM). Meanwhile, to determine the concentration of CO2 in biogas using Gas Chromatography (GC). The result showed that chitosan impregnated on activated carbon (0.1:1 w/w) can purify biogas up to 95 % compared to porous carbon.
