| 摘 要： | 以Ti-MWW为催化剂,研究了轻油中的有机硫模型化合物苯并噻吩和二苯并噻吩的氧化脱除. 结果表明,在343 K和乙腈为溶剂的条件下,苯并噻吩的转化率可达100%, 二苯并噻吩的转化率可达95%以上. 溶剂对苯并噻吩的氧化有很大影响,在相同的反应条件下,三种溶剂中苯并噻吩的转化率为乙腈＞甲醇＞水. 讨论了Ti-MWW催化氧化苯并噻吩的反应历程和溶剂效应.

| Abstract: | An oxidative desulfurization process for model light oil over Ti-MWW was investigated. Benothiophene and dibenothiophene are oxidized to their corresponding sulfoxides and sulfones, which can be removed by extraction using acetontrile. The conversion of benothiophene and dibenothiophene is 100% and 95%, respectively, at 343 K. The effect of solvent was also studied. Under the same conditions, the conversion of benzothiophene in three solvents is in the order acetonitrile>methanol>water. |
