Optimization of biodiesel production from Jatropha curcas L. oil via alkali-catalyzed methanolysis

บทคัดย่อ ( Abstract )

In this study, crude Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. The reaction in the presence of NaOH as catalyst was carried out to investigate the optimum conditions and to study the effects of variables on the reaction. These variables included methanol-to-oil molar ratios of 4:1-10:1, catalyst concentrations of 0.25-2.0% w/w of oil, reaction temperatures of 32-60ºC, and reaction times of 5-40 minutes. The methyl ester content in the product was analyzed by gas chromatography (GC). The optimum conditions for Jatropha curcas biodiesel production were a methanol-to-oil molar ratio of 6:1, a catalyst concentration of 1.0% w/w of oil, a reaction temperature of 60°C, and a reaction time of 40 minutes. The methyl ester content under these optimum conditions was 98.6% w/w, and all of the measured properties of the Jatropha curcas biodiesel met the Thai biodiesel (B100) specifications and international standards EN 14214:2008 (E) and ASTM D 6751-07b, with the exception of lower oxidation stability. The results reveal that all of the reaction variables in this study had positive effects on the reaction.
