以双氧水为氧化剂、磷钨酸？半焦（HPW？Sc）为催化剂、N-甲基吡咯烷酮为萃取剂、Span60为乳化剂，对以苯并噻吩（BT）、二苯并噻吩（DBT）、4，6-二甲基二苯并噻吩（4，6-DMDBT）为模型含硫化合物的模拟油进行氧化脱硫研究，考察磷钨酸负载量、氧化温度、氧化反应时间和模拟油中烯烃、芳烃和含氮化合物对含硫化合物脱除效果的影响。结果表明：催化剂的最佳磷钨酸负载量（w）为30％；在反应时间为60 min、反应温度为60℃、HPW？Sc2用量（w）为1.0％、Span60用量（w）为0.36％、n（H2 O2）？n（S）＝3的条件下，DBT脱除率可达到99％，含硫化合物的氧化活性由大到小的顺序为 DBT＞4，6-DMDBT＞BT；模拟油中的苯可促进 DBT的脱除，而喹啉和环己烯则抑制DBT的脱除。

Oxidative desulfurization of benzothiophene(BT,DBT and 4,6-DMDBT)in simulated oil was investigated using hydrogen peroxide as oxidant,Span60 as emulsifier,N-methyl pyrrolidone as ex-tractant and phosphotungstic acid?semi-coke (HPW?Sc)as catalyst.The HPW?Sc catalysts were charac-terized by FT-IR.The effect of HPW loading amount,reaction temperature,reaction time,and aromat-ics,olefins and nitrogen compounds on desulfurization rate was studied.The results show that the sul-fur removal efficiency of DBT reaches above 99% using the catalyst with 30% HPW loading at the con-ditions of temperature of 60 ℃,reaction time of 60 min,amount of catalyst 1.0%,n(H2O2)?n(S)=3, amount of Span60 emulsifier 0.36%,and the oxidative activity of the model sulfur compounds follows the order of DBT>4,6-DMDBT>BT. The benzene in the test oil can promote DBT desulfurization, while quinoline and cyclohexene inhibit the removal of DBT.
