| Summary: | Systematic experiments were conducted to investigate the most appropriate extraction conditions for sulfur reduction. Initial extraction studies showed that DMF was the most potentially effective solvent. The influence of DMF to diesel ratios, extraction times and temperatures, addition of co-solvent, solvent mixtures, double extractions were explored. The use of co-solvent and solvent mixtures showed poor efficiencies of sulfur removal. A two-stage extraction with ratio of 1:1 (DMF/Diesel) was successfully removed over 88.0% of sulfur in diesel. Under Box-Behnken design, the model showed that maximum extraction ability was observed at 30. °C, 30. min and 1.0 of DMF/diesel ratio to achieved 67.5%. |
