| 摘 要： | 以过氧化氢为氧化剂，Omim]PF6离子液体为萃取剂，C16mim]2 Mo2O11为催化剂建立了萃取催化氧化脱硫体系（ECODS）。该反应体系在非常温和的条件下可使DBT的脱除率最高达到99.4%，大大优于单纯的萃取脱硫和萃取氧化脱硫体系。不同硫化物在该体系下的脱硫效果为：DBT >BT >TH。催化体系循环使用10次后催化反应活性未见明显下降。将此催化体系直接用于市售的汽油和柴油，可使其中硫含量降低至12.70mg/L和11.62mg/L。

| Abstract: | The oxidation of aromatic sulfur compounds(dibenzothiopheneDBT],benzothiopheneBT] and thiopheneTH])was studied at 30℃ and in an extraction and catalytic oxidation desulfurization(ECODS) system composed of model oil,hydrogen peroxide,1-octyl-3-methylimidazolium hexafluorophosphate (Omim]PF6) and a peroxomolybdate catalystC16mim]2 Mo2O11(C16mim=1-hexadecy-3-methylimidazolium). In this system,the removal rate of DBT could reach as high as 99.4% under mild conditions,which was superior to that of the simple chemical oxidation or extraction combined chemical oxidation. The catalytic oxidation reactivity of the different substrates decreased in the order:DBT>BT>TH. The catalytic system could be recycled ten times without a significant decrease in catalytic activity. The system was also applied to commercial gasoline and diesel oil,and the resulting sulfur content decreased to 12.7mg/L and 11.6mg/L,respectively. |
