The Relationship between Elemental Form of Solid Phase and COS Formation over MnO_X Desulfurization Sorbent

Abstract:

Three different kinds of MnOx desulfurization sorbent were prepared by different calcination temperature and reduction method. The properties of H₂S removal and COS formation over the prepared MnOx were measured in the fixed bed at 550°C, and the MnOx phases before and after desulfurization were characterized by XRD and XPS. The results show that the sequence of the amount of COS formation over three MnOx samples is Mn₃O₄>Mn₂O₃>MnO, and the sequence of H₂S penetration time is Mn₃O₄2O₃2 are good for COS formation. With the single sulfur and MnS₂ accumulated in MnOx desulfurization sorbent, the more and more the amount of COS formed during desulfurization.
