Describes an experiment with oxidative desulfurization (ODS) of diesel fuels with new extragents. A mixture of a commercial diesel oil (100 mL), 30 wt % hydrogen peroxide (3 mL), H2O (5 mL), formic acid (4 mL), and W101 (0,7 g) was stirred at 750 rpm in a 250-mL, three-necked flask at 60 °C for 60 min.
The flask was fitted with a condenser, a mechanical stirrer, and a thermometer. After the completion of the reaction, the oxidized oil, which was separated from the reaction mixture, was washed with an aqueous solution of sodium carbonate (5 wt %, 50 mL 2), and then dried over anhydrous sodium sulfate. Adsorption of the sulfur compounds remained in the oil after drying was performed in a glass flask with a stirrer. The oxidized oil (97,8 mL) and adsorbent (1,5 g of W101, 20 g of Al2O3) were mixed at room temperature for 12 h, and then the oil and adsorbent were separated by filtration‖[2].
Sulfur contents after oxidation of the commercial diesel oil using different ODS systems have been summarized in table 1.
