With growing concern about the environment, the oil industry has become interested in new technologies that reduce costs by increasing the efficiency of removing sulfur compounds from fossil fuels. Oxidative desulfurization is an interesting sulfur-removal process for the petroleum industry because it uses mild reaction conditions. In this work, zeolites (ZSM-5, NaX, NaY, Beta and Mordenite) impregnated with 1% vanadium or manganese were used for the oxidation and extraction of dibenzothiophene (DBT) from a diesel load. The catalysts were characterized by X-ray diffraction, N₂ adsorption-desorption textural analysis and scanning electron microscopy, and the reaction products were analyzed by gas chromatography (GC-FID). It was found that vanadium or manganese impregnation did not significantly modify the structure of the zeolites. The vanadium-impregnated zeolite ZSM-5 showed the best result in the oxidation of dibenzothiophene, oxidizing up to 80% of the DBT added in the diesel charge (ZSM-5 5020 V). The manganese-based catalysts were not as active for this oxidation, and the best performance was found for the removal of DBT by extraction.

随着对环境的日益关注，石油工业对通过提高从化石燃料中去除硫化合物的效率来降低成本的新技术感兴趣。氧化脱硫是石油工业中一种有趣的脱硫方法，因为它使用的反应条件温和。在这项工作中，将浸渍有1％钒或锰的沸石（ZSM-5，NaX，NaY，Beta和丝光沸石）用于氧化和从柴油负载中萃取二苯并噻吩（DBT）。催化剂通过X射线衍射N ₂表征。吸附-解吸织构分析和扫描电子显微镜，并通过气相色谱（GC-FID）分析反应产物。发现钒或锰的浸渍不会显着改变沸石的结构。钒浸渍的沸石ZSM-5在二苯并噻吩的氧化中表现出最好的结果，氧化了柴油装料（ZSM-5 5020 V）中添加的DBT的80％。锰基催化剂对这种氧化没有活性，并且发现通过萃取去除DBT的最佳性能。
