Abstract—Hydrogen sulfide (H
2S) 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 H2S 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
2S, 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.
