Abstract
Biogas is purified before being used in from the acid content of sulfide (H2S), although the numbers are small, but the resulting loss due to corrode metal or when burned to form SO2 or SO3, known as SOx that cause acid rain. The purpose of this study to find time in the saturated adsorbent adsorb H2S, the ability of the activated carbon adsorbent adsorb adsorption equation and find the constants in the Freundlich isotherm variations in the size of activated carbon for in calculating the residence time of adsorption. The materials used are the sludge from the hospital wastewater treatment. The method was performed in this study for measure the content of H2S in the biogas before passed through to the third adsorber column 70 cm height, ½ inch diameter, 64 cm high filling packing material of activated carbon with a size of 4, 7, 10, 12, 14 mesh velocity biogas 0 , 5 litre. / min obtained results most rapidly activated carbon burnout mesh size of 4 is 60 minutes, H2S is adsorption 202.42 mg of 9.76% while the efficiency of saturation saturation time exceeding 90 minutes 14 mesh size activated carbon is adsorption H2S 368.65 mg 9.79% saturation efficiency. Optimal use of activated carbon which is 12 mesh saturated 80-minute time, efficiency saturated 9.82% with a residence time of 127.927 seconds while the shortest residence time occurs on the mesh size of adsorbent 4, the residence time of 73.855 seconds.
