In this paper, Mesoporous silica gel (SG) and SBA-15 modified with methyl-diethyl-amine (MDEA) were prepared and used to removal H₂S from the model gas with 200ppmv H₂S. The adsorbents were characterized by X-ray powder diffraction (XRD) and N2 adsorption/desorption. The characterization results showed that the loaded MDEA could not change the structure of the adsorbents. The removal performance of H₂S on the adsorbents was conducted in a dynamic setup. Effect of different adsorbent and effect of adsorption temperature on removal performance of H₂S were studied respectively. Adsorbents after modifying with MDEA showed better removal H₂S performance than before modifying with MDEA. Variation of temperature would have minor affection. The results indicated that the MDEA modified adsorbents were novel for removing H₂S.
