Biomass adsorbents were prepared from fallen oak leaves. In the activation process for fallen oak leaves, various operating parameters such as the activation temperature (600-900°C), steam injection rate (5-15 cc/hr), and steam injection time (1- 3 hr) were adopted. For analyses of the manufactured adsorbent, various methods such as scanning electron microscope (SEM), measurements of the BET surface area and chemical composition analyses were adopted. Regarding major adsorption characteristics, the adsorption equilibrium capacity was measured using batch type experimental apparatus for various biomass adsorbents. The experimental result showed that the H2S adsorption equilibrium capacity of the adsorbent made from fallen oak leaves decreased as the activation temperature and steam injection rate increased for a given range.
