The oxidation of dibenzothiophene (DBT) was conducted using t-butyl hypochlorite (t-BuOCl) in the presence of several catalysts. In a flow reactor under ambient pressure at 30-70°C, more than 90% of DBT could be oxidized in the decahydronaphthalene (decalin) solution. The catalyst was necessary to oxidize dibenzothiophene with t-BuOCl, and γ-alumina (Al2O3) supported catalysts have relatively high activities. At the same time, the activities of the metal-loaded Al2O3 catalysts had shown the same activities as those of the Al2O3 support, indicating that the Al2O3 support itself possessed such activity. Further, the effect of a variety of model compounds found in light gas oil (LGO) such as n-pentadecane, 2, 4, 4-trimethylpentene, xylene, and indole on the oxidation of DBTs were also investigated.
