Abstract

A desulfurization process for model oil and real oil was investigated based on the chemical oxidation of mixed sulfur containing compounds in the presence of nitrogen compounds indole and quinoline using hydrogen peroxide as oxidizing agent and dodecamolibdophosphoric acid H3PMo12O40 encapsulated in a kind of metalorganic framework HKUST1 as PMoHKUST1 The effect of isopropanol ethanol and acetonitrile as extractive solvent and 1ring toluene xylene and mesitylene and 2ring naphthalene aromatic hydrocarbons in desulfurization of model oil was studied The desulfurization of sulfurcontaining compounds was accelerated in the presence of aromatic hydrocarbons In fact a higher desulfurization efficiency of the heterogeneous catalyst could be achieved with system containing a polar solvent in contact with an aromatic hydrocarbon Quinoline had no effect on oxidative desulfurization ODS reaction whereas indole had a slightly negative effect Presence of aromatic compounds had slightly positive effect on ODS reaction
