Abstract
We evaluated the adsorption of CO<sub>2</sub> 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 CO<sub>2</sub> 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 CH<sub>4</sub>. The relationship between the percentage of CH<sub>4</sub> composition and calorific value of biogas was investigated. The results of data from GC showed that the highest CH<sub>4</sub> 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 CO<sub>2</sub> adsorption using natural zeolite and chicken manure based biochar successfully increased the calorific value of biogas.
