Preparation of Manganese Dioxide Loaded Active Carbon and its Adsorption Dynamic

Article Preview

Abstract:

Manganese dioxide loaded active carbon absorbents (MnO2/AC) were prepared. Mixture of H2S and N2 is used to evaluate the performance of absorbents in fixed adsorption bed for H2S removal. A suitable H2S removal activity was obtained with adsorbent of manganese dioxide to active carbon ratio of 1:1, drying temperature of 120°C, drying time of 24 h. The breakthrough time of 70 min with total gas volume of 1400 mL, adsorption temperature of 40°Cwere observed. Comparing with the unmodified active carbon, its breakthrough H2S capacity increased by 96.9 mg·g-1.
