Biodiesel Synthesis

Synthesis of biodiesel from rubber seed oil using a supercritical methanol was investigated under various reaction conditions (220 - 300°C, 80 - 180 bar) with reaction time of 1-15 min and oil:methanol molar ratio of 1:20 - 1:60. Free fatty acid methyl esters (FAMEs) content were analyzed by gas chromatography-mass spectroscopy (GC-MS). Most properties of produced biodiesel were in good agreement with biodiesel standard (EN 14214). The maximum FAME yield of 86.90% was obtained at 260°C, 160 bar, 5 min reaction time using oil:methanol molar ratio of 1:40. The result showed the acid value of rubber seed oil decreased to 0.58 mgKOH/g from initial 24 mgKOH/g to. It could be concluded from this findings that crude rubber seed oil is a promising alternative raw material for biodiesel synthesis via supercritical methanol tranesterification.
