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.
作为一种常见的鸟类饲料原料，埃塞俄比亚画眉草种子已被探索用于生物柴油合成的潜力。通过溶剂萃取法从种子中提取油脂，并对埃塞俄比亚画眉草油的成分进行了检测。对生物柴油合成的反应参数进行了优化。发现温度、油与甲醇的比例、催化剂类型和催化剂浓度对酯转化率有显著影响。根据这项研究，在65摄氏度的操作温度下，使用优化的甲醇钠催化剂用量（0.6%）可获得最高酯产率（98.7%）。还对埃塞俄比亚画眉草油的甲酯的氧化稳定性和低温性能进行了研究。此外，将合成产物以5%-20%的比例与柴油混合，并对其理化性质进行了评估。
