| 摘 要： | 二苯并噻吩（dibenzothiophene DBT）及其衍生物是重油、减压馏分油及渣油中的主要硫化物。在通常的加氢脱硫中，二苯并噻吩系列是较难脱除的一类有机硫。近年来，以二苯并噻吩系列为模型的深度脱硫研究发展迅速。李建源等对二苯并噻吩及其衍生物为模型的氧化脱硫（Oxidative desulfurization ODS）、加氢脱硫、吸附脱硫及生物脱硫等作了较为详尽的报道。

| Abstract: | The oxidation of dibenzothiophene (DBT) in decalin (as solvent) was conducted using oil-soluble oxidant cyclohexanone peroxide (CYHPO).The effects of oxidant amount, reaction temperature, reaction time were investigated in detail. The results showed that under the condition of ratio of CYHPO to sulfur 2.5∶1, reaction temperature 100℃ and reaction time 3h, the desulfurization rate was up to 87%. The little water produced after oxidation was removed by molecular sieve adsorption. The recovery ratio of model oil was up to 98% after the treatment with centrifugation and adsorption. |
