KOH를 함침시킨 활성탄 흡착제의 H₂S 흡착특성

H₂S adsorption characteristics of KOH impregnated activated carbon adsorbent

H2S adsorption characteristics of the impregnated activated carbon adsorbent were investigated. KOH reagent was used for impregnating the activated carbon. For analyses of the impregnated activated carbon adsorbent, various methods such as TGA test and acid-base titration. as well as measurements of BET surface and pH were adopted. As operating variables, adsorption temperature (25~45℃) and H₂S concentration (4. 96~ 18.23mg/ℓ) were applied. The experimental results showed that the H₂S adsorption equilibrium capacity of KOH impregnated activated carbon adsorbent increased with increasing temperature and H₂S concentration.
