In this paper, organic-inorganic heteropolyacids were prepared, including [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆], [π-C₅H₅NC₁₆H₃₃]₃[PMo₄O₁₆], [π-C₅H₅NC₁₂H₂₅]₃[PW₄O₁₆] and [π-C₅H₅NC₁₂H₂₅]₃[PMo₄O₁₆]. The efficiency of oxidative desulfurization was investigated on the four kinds of catalysts under the same conditions using the simulated oil prepared by dissolving organo-sulfur in normal octane. The results show that the catalytic activity of [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆] is the best. The catalytic activity of these heteropolyacids was following the order of [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆]>[π-C₅H₅NC₁₂H₂₅]₃[PW₄O₁₆]>[π-C₅H₅NC₁₆H₃₃]₃[PMo₄O₁₆]>[π-C₅H₅NC₁₂H₂₅]₃[PMo₄O₁₆]. Under the optimal experimental conditions, pre-reaction time between H₂O₂ and the catalyst being 10 min, reaction temperature being 60 ℃, O/S molar ratio being 10, the amount of catalyst being 1 wt% of n-octane, and the catalyst being [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆], the dibenzothiophene (DBT) conversion was nearly 100% after 60 min. The catalyst [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆] can be reclaimed by auto precipitation due to the exhausting of H₂O₂. The results show that organic-inorganic heteropolyacids are phase transfer catalyst and oxidative desulfurization system belongs to the phase transfer catalysis system controlled by reaction. The catalytic activity of the recycled [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆] is almost the same as the fresh. Then, the efficiency of oxidative desulfurization was investigated with different simulated oils using DBT, thiophene (TH), benzothiophene (BT) and 4,6-dimethyldibenzothiophene (4,6-DMDBT), respectively. Under the same conditions, the efficiencies of oxidative desulfurization decrease in the order of DBT>4,6-DMDBT>BT>TH, the result was influenced by electron density on the sulfur atoms and the steric hindrance. It showed that the final desulfurization product of TH, BT, DBT and 4,6-DMDBT was SO₄^2-,SO₄^2-, DBT sulphone and 4,6-DMDBT sulphone, respectively. [π-C₅H₅NC₁₆H₃₃]₃[PW₄O₁₆] used in desulfurization of the real diesel and the sulfur removal rate was 92.7%. The sulfur content was reduced from 355 mg/kg to 26 mg/kg. Furthermore, by studying the kinetics of DBT oxidation by H₂O₂, the reaction order was found to be 1st to DBT. The activation energy ranged from 47.9 kJ/mol to 55.4 kJ/mol by different organic-inorganic heteropolyacids. It indicates the reaction process is quite fast in ODS. The new type of catalysts has a broad development prospect in oil desulfurization.
