title: Studies on Guizotia abyssinica L. oil: biodiesel synthesis and process optimization.
abstract: Guizotia abyssinica seeds, a common bird feedstock, have been explored for the potential of biodiesel synthesis. The oil was extracted from the seeds by solvent extraction and composition of G. abyssinica oil was examined. The reaction parameters for biodiesel synthesis have been optimized. Temperature, oil: methanol ratio, catalyst type and catalyst concentration were found to have significant role on ester conversion. According to this study, the maximum yield of ester (98.7%) can be obtained with optimized sodium methoxide catalyst dosage (0.6%) at an operational temperature of 65 degrees C. Methyl ester of G. abyssinica oil was also studied for its oxidation stability and low temperature properties. Further, the synthesized product was blended in diesel at 5-20% ratios and evaluated for physico-chemical properties.
