Abstract—We evaluated the adsorption of CO2 in biogas mixtures using the combination of adsorbents: natural zeolite-natural zeolite (Z-Z), natural zeolite-chicken manure based biochar (Z-CM) and natural zeolite-biogas sludge based biochar (Z-BS). The amount of CO2 adsorption was controlled at room temperature and under a gas pressure range of 5-7 bar. Samples of biogas before and after adsorption were analyzed by gas chromatography (GC) to determine the percentage of CH4. The relationship between the percentage of CH4 composition and calorific value of biogas was investigated. The results of data from GC showed that the highest CH4 enrichment was performed by Z-CM (28.92%). The highest CH4 enrichment increased the calorific value of biogas in comparison to biogas before adsorption. The result suggested that CO2 adsorption using natural zeolite and chicken manure based biochar successfully increased the calorific value of biogas.
