Sažetak

The improving of motor fuels quality with regard to ecological standards is directed continuously toward lower sulfur content, which can be achieved by different desulfurization methods. The oxidative desulfurization process is developed as an alternative or addition to the hydrodesulfurization processes.
In this paper the effects of reaction temperature, rate of stirring and time of oxidation of model diesel fuel with hydrogen peroxide/acetic acid in 70 ml batch reactor were investigated. The temperature range was 20-90 °C, rate of stirring 300-700 rpm, and reaction time up to 150 minutes. The results indicate a rise in the yield of sulfones at higher temperatures and higher rate of stirring.
Extraction with N,N-dimethylformamide was conducted after the process of oxidation and the effect of solvent/oil ratio, rate of stirring and temperature was investigated. Gas chromatography method was used for identification of sulfur containing compounds formed during the oxidative desulfurization process.
