Roselle (Hibiscus sabdariffa L.) oil as an alternative feedstock for biodiesel

บทคัดย่อ ( Abstract )

The production of biodiesel fuel from crude roselle oil was evaluated in this study. The process of alkalicatalyzed transesterification with methanol was carried out to examine the effects of reaction variables on the formation of methyl ester: variables which 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 32–60 C, and reaction times of 5–80 min. The methyl ester content from each reaction condition was analyzed by gas chromatography (GC), the optimum condition having been achieved at a methanol-to-oil molar ratio of 8:1, a catalyst concentration of 1.5% w/w of oil, a reaction temperature of 60 C, and a reaction time of 60 min. The resultant methyl ester content of 99.4% w/w, plus all of the other measured properties of the roselle biodiesel, met the Thai biodiesel (B100) specifications and international standards EN 14214:2008 (E) and ASTM D 6751-07b, with the exception of a higher carbon residue and lower oxidation stability.
