Study the Removal of Sulfide in MTBE Base on the Attapulgite Desulfurizer

Abstract:

A novel desulfurizer was prepared to remove the sulfide in MTBE. The performance of the desulfurizer was investigated by L₁₈(2×3⁷) Orthogonal Test. The desulfurizer for MTBE was prepared by the impregnating technique, in which the transitional metal Fe series and Ag series compounds were used as active components, and the modified attapulgite clay as the carrier. In order to get the optimum conditions to desulfurization in MTBE, IR, XRD, TEM, XPS technology were used to study the desulfurization mechanism. Compare the desulfurization characterize before and after the experiment. The result shows that the desulfurizer made by 8% Fe series compound and 2% Ag series compound, and roasted at 300°C for 3 hours. The Sulfur content in MTBE was reduced from 789mg/kg to 124mg/kg. The desulfurization rate was reached to 84.18% (in normal temperature and pressure.). The removal effect is obvious. The result of this study can be applied for Removal sulfide in MTBE.
