N2 - In order to utilize biogas, hydrogen sulfide/H2S impurities reduction is needed to maximize methane/CH4 content. Although H2S amount is relatively non-dominant, its presence can trigger corrosion, and is harmful to health and environment. Steel wool can be used as adsorption media to reduce H2S content. This study was conducted to identify the characteristics of steel wool and H2S concentration reduction efficiency. Biogas was flown to a PVC column (2 inches diameter) containing steel wool. The results showed that steel wool media contain active elements of Fe and Zn which are spread evenly on the media surface with a total amount of 97.5% mass. The concentration of H2S at inflow ranged from 68 to 111 ppm with the outflow of 21.2-0 ppm, and the temperature in the system varied between 29-33 °C. Optimal H2S removal efficiency reaches 97% in average, obtained at 100 cm column height and flow rate of 0.1 L/min. It can be concluded that the steel wool media has high content of active element and can reduce H2S content in biogas at ambient temperature condition.
