Synthesis and characterization of amorphous mesoporous materials impregnated with Hematite (Fe2O3) for use in the H2S removal

Abstract

In this work, three amorphous mesoporous materials (MMD1, MMD2, and MMD3) with different structural characteristics were synthesized and impregnated with 10% of Fe₂O₃, in-order-to obtain an effective amorphous mesoporous material (MMD) for H₂S adsorption. These materials were characterized by using SEM, EDX, TEM, ICP-MS, N₂ Adsorption, and DRX. Capacity tests for H₂S adsorption were performed to evaluate its performance as adsorbents of this gas. The results showed that the MMD1 mesoporous material impregnated with Fe₂O₃ showed the highest adsorption capacity of H₂S concerning the other materials studied in this work. This material could be a good option to control environmental emissions and improve the quality of the oil and gas.
