The long-term objective of this research is to obtain biogas with renewable natural gas quality and can be used as fuel for electric generators to support the availability of electricity in small island areas. The specific target to be achieved is to obtain methods / techniques to reduce impurity levels contained in biogas, especially hydrogen sulfide gas, comprehensive technology information and active ingredients to absorb hydrogen sulfide gas as materials for writing textbooks and articles for national journals. This research will be tested to reduce levels of H2S (hydrogen sulfide) in biogas using ferric oxide (Fe2O3) absorbent. In this study, the variables studied were the effect of the biogas flow rate on absorbed hydrogen sulfide (H2S) and the resulting CH4. H2S absorption was carried out by feeding biogas into the ferric oxide absorbent continuously at a certain biogas flow rate (1, 3, 5, 7 and 9 l / min). Then the research was continued by determining the levels of H2S absorbed and CH4 produced using the biogas tester set type atex directive. The increasing of the biogas flow rate that passes through the absorber tube containing Fe2O3, the smaller the H2S gas that can be absorbed by Fe2O3, this is because the time to react between H2S and Fe2O3 is getting smaller or less, so that the reaction that occurs is still not perfect, the biogas has left the tube. absorber. In this study, biogas with a flow rate of 1 liter / minute, obtained the best absorber ability to absorb H2S, namely H2S lagging an average of only 14.43 ppm from 1314 ppm contained in biogas, or nearly 98.9% which can be absorbed. Meanwhile, the level of metane gas (CH4) did not change during the purification process.
