This research aimed to 1). perceive the abilities of various types of adsorbents towards the percentage of CH4 (biomethane) and 2). determine the potential types of adsorbents to increase the percentage of CH4. The first experiment was P which consisted of P0, P1, P2, P3, P4 and P5; each of them contained grit of chicken waste adsorbent (BLAR) and chicken eggshell (CTAR). Then, the second experiment was T which consisted of T0, T1, T2, T3, T4 and T5; each of them contained BLAR and hydrated lime (KP). The measured variables were (1). biogas volume (dm3), (2). filtration rate (second), (3). percentage of filtered CO2, (4). percentage of CH4 produced. The observation results from the first and second experiment had a highly significant effect (P <0.01) on all four variables except for the second experiment on the biogas filtration rate which had a significant effect (P <0.05). Thus, it could be concluded that (1). P1, P2, P4, and T2 were the adsorbents which were able to purify animal manure biogas into biomethane and (2). the potential adsorbent in filtering biogas was 100% BLAR or the addition of CTAR or KP up to 75%. © Published under licence by IOP Publishing Ltd.
