Many researchers are currently developing the best method to reduce the total sulfur content in fuels, such as the Catalytic Oxidative Desulfurization (Cat-ODS) method. The Cat-ODS oxidizes sulfur compounds in diesel oil to sulfur oxides, which have more polar and reactive characteristics. In this study, the Cat-ODS method conducted by oxidation process followed by liquid-liquid extraction using H2O2 (oxidizer), CH3COOH (catalyst), and CH3OH (solvent). FTIR is used to analyze the total sulfur content. The condition with oxidation temperature of 50°C, extraction stirring time of 40 minutes, and solvent/Biosolar volume ratio of 1:4 provides the highest desulfurization rate, 26.1%.
