Heteropolyanion Substituted Layered Double Hydroxide as Recoverable Catalyst for the Oxidative Desulfurization of Simulated Fuel Oil and Diesel

Abstract:

Heteropolyanion substituted layered double hydroxide were synthesized and used as catalysts for oxidative desulfurization in simulated fuel oil (dibenzothiophene (DBT) in n-octane) or diesel. The catalysts are recoverable and operate with high conversion efficiency under mild conditions of atmospheric pressure and 60 °C in a biphasic system using peroxide hydrogen as oxidant and acetonitrile as extractant. Zn₉Al₃(OH)₂₄PW₁₂O₄₀(ZnAlPW), Zn₉Al₃(OH)₂₄PMo₁₂O₄₀ (ZnAlPMo) and Zn₁₂Al₄(OH)₃₂SiW₁₂O₄₀(ZnAlSiW) were identified as effective catalysts for the oxidative removal of DBT from simulated fuel oil. The order of decreasing catalytic activity is ZnAlPMo > ZnAlPW > ZnAlSiW. The results show that the best catalysts, ZnAlPMo, attained to a DBT conversion of nearly 100%. All the catalysts can be readily recycled by filtration after use. The recoverable ZnAlPMo retains nearly the same catalytic activity as the fresh. ZnAlPMo was found to exhibit an ideal catalytic activity in oxidative desulfurization of diesel with a total sulfur removal rate of 91.8%.
