H2S adsorption characteristics of adsorbent made by coffee waste were investigated. The manufacturing method of adsorbent is to activate the coffee waste with steam after carbonization of dried coffee waste. For analyses of the manufactured adsorbent, various methods such as scanning electron microscope (SEM), measurements of BET(Brunauer Emmett Teller) surface area, pH, and Iodide adsorption were adopted. As major adsorption characteristics, adsorption equilibrium capacity was measured by using a batch type experimental apparatus for operating variables such as adsorption temperature (25~45℃), adsorbent types. The experimental result showed that the H2S adsorption equilibrium capacity of adsorbent made by coffee waste much more increases with steam activation for the coffee waste.
