Abstract-Hydrogen sulfide (H 2 S) is found in the biogas as an impurities. The existence of hydrogen sulfide in the biogas resulting problematic for using biogas as a fuel since it will increase the acidity of the lubricant of the engine. Hydrogen sulfide is a corrosive gas that can corrodes the steel tank of biogas container. Other serious problem concerning H 2 S is, this type of gas is a harmful gas that should be avoided. This work introduces a technique to utilize aluminium chips waste that is obtained from manufacturing process. To make aluminium chips reactive to H 2 S, the ion Al 3+ should be released from the aluminium by galvanic coupling with iron in salt water. The iron uses for this purpose also come from the iron chips waste. It is found the more addition of iron chips in to the mixture of aluminium + iron the more reactive the aluminium as desulfurizer Index Terms-Aluminium, desulfurizer, galvanic coupling, hydrogen sulfide. I. INTRODUCTIONHydrogen sulfide (H 2 S) has to be removed before combusted to prevent environmental problem caused by emission of sulfur (S) compound, for reason of toxicity, and corrosion on equipment [1]. Foam formation was introduce in the early beginning for the removal of H 2 S from the gas stream [1], but this technique was not attract the customer because the reason of simplicity, especially for the consumer from developing country.A few years later Lee et al.[2] introduce method of sulfate-resistant Acidithiobacillysthiooxidans AZ11 for removal of H 2 S. This technique also not much attract attention from the consumer because it was not easy to handle the bacteria for this process.An interesting idea by utilizing waste was introduced by Yuan and Bandosz [3]. The waste that was used come from sewage sludge and metal sludge of various compositions. But this technique becomes not appropriate from economic point of view because the sludge should be pyrolysed at quite high temperature. Similar with work of Yuan and Bandosz [3], which is using waste for desulfurizer, Seredych [4] also using wastes i.e. fly ash for desulfurizer. But this technique become not popular since pyrolyses process is needed at higher temperature (950 o C).The idea of using natural product such as zeolite as Manuscript received November 5, 2013; revise February 17, 2014. The authors are with the Department of Mechanical Engineering, Engineering Faculty, Udayana University Jimbaran, Bali, Indonesia, 80361 (e-mail: nindhia@yahoo.com).desulfurizer was introduced by Cosoli et al. [5]. Zeolite is a mining product with reasonable price but not available every where. Only in certain region we can find zeolite sources from mining. Cost to delivery zeolite from mining location to the place of biogas installation could be another problem.Recently the research on promoting metal chips waste as desulfurizer was conducted by Nindhia et al. [6]. By utilizing steel chips waste, the regenerative type of desulfurizer can be developed. This type of desulfurizer can be use repetitively and already successful as a compon...

Abstract-The existence of hydrogen sulfide(H 2 S)as impurities in the biogas resulting problematic for using biogas as a fuel since it will increase the acidity of the lubricant of the engine. Hydrogen sulfide is a corrosive gas that can corrodes the steel tank of biogas container. Other problem concerning H 2 S is, this type of gas is a harmful gas that should be avoided. This work introduces a technique to utilize copper alloy chips waste that is obtained from manufacturing process. By galvanic coupling with iron chips in salt water the Fe 2+ is released on the surface of iron chips and react with H 2 S to produce FeS. The iron chips that are used for this purpose also come from the iron chips waste. It is found the more addition of iron chips in to the mixture of copper chips the more reactive the desulfurizer.Index Terms-Copper, galvanic, coupling, biogas, desulfurizerhidrofen sulfide. I. INTRODUCTIONHydrogen sulfide (H 2 S)impurities in the biogas has to be removed before combusted to prevent toxicity, environmental problem caused by emission of sulfur (S) compound, and corrosion on equipment [1].Some method for desulfurization that was established such method of sulfate-resistant Acidithiobacillysthiooxidans AZ11 [2].

The waste that was used come from sewage sludge and [6]. By utilizing steel chips waste, the regenerative type of desulfurizer can be developed. This type of desulfurizer can be use repetitively and already successful as a component for conversion of gasoline to biogas fueled single cylinder of four stroke engine of electric generator [7].The metal waste from manufacturing industry are not only steel of iron but other type such as aluminium chips waste are much available because many component of the engine are made from aluminium. Aluminium is not reactive to H 2 S even though in the form of aluminium oxide but can be used as desulfurizer [8] with galvanic coupling method [9].The remaining of metal chips waste is copper alloy such as brass. It is the purpose of this research to use the waste of copper alloy chips as desulfurizer by using galvanic coupling method. Galvanic coupling is a potential difference that exists between two joined dissimilar metals immersed in electrolyte solution. The potential difference yield electron flow and metal ion will be released from one of the coupling [9]. The metal ion will react with H 2 S in ...
