Abstract—Aerobic oxidation of organosulfur compounds of petroleum origin by atmospheric oxygen was performed using a heterogeneous catalyst in the form of Fe₃O₄ nanoparticles. By studying the oxidation of model mixtures (a solution of dibenzothiophene in decalin), the following conditions for the complete oxidation of dibenzothiophene were selected: catalyst weight, 1 mg; temperature 130°C; and time, 180 min. The catalyst remains active throughout five oxidation cycles. Physicochemical studies showed that the phase composition and structure of the catalyst persist after the regeneration stage.

有机硫化合物在 Fe3O4 纳米颗粒存在下的有氧氧化作用

摘要--使用 Fe3O4 纳米颗粒形式的异相催化剂，利用大气氧对石油来源的有机硫化合物进行了有氧氧化。通过研究模型混合物（二苯并噻吩在癸醛中的溶液）的氧化情况，选定了二苯并噻吩完全氧化的以下条件：催化剂重量为 1 毫克；温度为 130°C；时间为 180 分钟。催化剂在五个氧化循环中始终保持活性。理化研究表明，催化剂的相组成和结构在再生阶段后仍然存在。
