Abstract—The carbon rod of used zinc-carbon battery was investigated in this research to be recycled as biogas desulfurizer. The carbon rod was taken out from the used battery and crushed to become a pellet with about 1 cm long. To increase its performance, the carbon rod was put in solution of KMnO4 and water then tested its performance as desulfurizer. It is found that the performance of desulfurizer increase by putting about 200 gram of carbon rod in the solution of KMnO4 with minimum concentration of 20 gram KMnO4 /liter water. It is suggested during application to use low flow rate of biogas (around 1-3 liters/minute) to achieve maximum performance.
Index Terms—Carbon rod, zinc-carbon, battery, biogas, desulfurizer, performance.
