Abstract—The existence of hydrogen sulfide(H2S)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 H2S 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 Fe2+ is released on the surface of iron chips and react with H2S 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.
