Systematic experiments were conducted to investigate the most appropriate extraction conditions forsulfur 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, solventmixtures, double extractions were explored. The use of co-solvent and solvent mixtures showed poorefficiencies of sulfur removal. A two-stage extraction with ratio of 1:1 (DMF/Diesel) was successfullyremoved over 88.0% of sulfur in diesel. Under Box–Behnken design, the model showed that maximumextraction ability was observed at 30 8C, 30 min and 1.0 of DMF/diesel ratio to achieved 67.5%.
