Formation of (FexMn2−x)O3 solid solution and high sulfur capacity properties of Mn-based/M41 sorbents for hot coal gas desulfurization

► High quality of MCM-41 was prepared from cheap and available industrial water glass. ► Formation of (FexMn2−x)O3 solid solution enhanced greatly sulfur capacity of sorbent. ► Mesoporous structure of FexMnyOz/M41 improved the diffusion rate of H2S molecules. ► Result of XRD, XPS and LRS verified that (FexMn2−x)O3 species was mainly active phase.
