Biodiesel is a green renewable energy source and an alternative for diesel fuel. The objective of this research was to study the feasibility of biodiesel production from Celtis australis L. oil using an ultrasonic system and CaO derived from chicken bone as a biowaste renewable resource. In this research, the effects of some parameters such as the alcohol-to-oil molar ratio (6:1, 9:1, 12:1), the CaO catalyst concentration (3%, 5% and 7% w/w), and the reaction time using ultrasonication (10, 25, 40 min) on the rate of conversion of fatty acids to methyl ester (biodiesel) were studied. The results showed that by increasing the molar ratio into the range between 6:1 and 9:1, the conversion percentage first increased and then its value followed a fixed trend. By increasing the catalyst concentration to about 5%, the conversion percentage increased significantly, and then remained constant. By increasing the time from 10 to 25 min, the conversion percentage increased by 20.19%, but from 25 to 40 min, no significant difference was observed. Moreover, all of the properties of C. australis methyl ester were found to meet the requirements of EN 14214 (European Committee for Standardization) biodiesel standards.

利用鸡骨催化剂和超声波从澳大利亚Celtis australis L.油生产生物柴油的可行性和优化

生物柴油是一种绿色可再生能源,也是柴油的替代品。这项研究的目的是研究从澳大利亚Celtis生产生物柴油的可行性使用超声系统的L.油和源自鸡骨的CaO作为生物废物可再生资源。在这项研究中,某些参数的影响,例如醇与油的摩尔比(6:1、9:1、12:1),CaO催化剂浓度(3%,5%和7%w / w) ,并研究了超声处理反应时间(10、25、40分钟)对脂肪酸向甲基酯(生物柴油)转化率的影响。结果表明,通过将摩尔比增加到6:1和9:1之间的范围,转化率首先增加,然后其值遵循固定趋势。通过将催化剂浓度增加至约5%,转化率显着增加,然后保持恒定。通过将时间从10分钟增加到25分钟,转化百分比增加了20.19%,但从25分钟增加到40分钟,没有观察到显着差异。而且,所有的特性发现澳大利亚梭菌甲酯符合EN 14214(欧洲标准化委员会)生物柴油标准的要求。
