Abstract
The purpose of the present study is to examine characteristics of hydrogen sulfide adsorption using iron-activated carbon composite adsorbents prepared by ferric nitrate and ferric chloride. Prepared adsorbents were discussed on H2S adsorption capacity. Also, adsorbents were analyzed by surface analysis methods for illustrating the physical characteristics of H2S adsorption. The breakthrough tests of H2S were conducted at 3,333 ppm of inlet concentration, demonstrating that the adsorption capacity for iron-activated carbon composite adsorbents was in order of FC_AC (Ferric chloride_Activated carbon), FN_AC (Ferric nitrate_Activated carbon), FC (Ferric chloride) and FN (Ferric nitrate). Adsorption capacity of FC was 0.06 g/g, whereas FC_AC showed the highest capacity of 0.171 g/g. All adsorbents exhibited the amorphous type in physical appearance based on XRD analysis and high Fe content based on EDS analysis. The surface areas of composites were increased by adding activated carbon, exhibiting better adsorption capacity.
