The adsorption of hydrogen sulfide gas on the thirty kinds of adsorbents (ten kinds of silicates, ten kinds of active carbons, and ten kinds of zeolites) was measured gravimetrically using Brunauer, Emmett, Teller (BET) apparatus with spring balance at 30°and 50 mmHg in order to find out the most suitable adsorbent for the hydrogen sulfide gas removal by a dry process. Among the thirty adsorbents, No. 23 (synthetic zeolite F-9) showed the largest amount of adsorption (mg/g). The relations between the amount of H2S adsorbed per unit surface area (mg/m2) and surface properties, the porous structure were investigated through surface pH, acid strength, acidity, basicity, adsorption isotherms, and pore size distribution. The adsorption of hydrogen sulfide gas (mg/m2) on the adsorbents except the active carbons was mainly determined by the porous structure of the adsorbents.
