Jojoba seed is an attractive alternative energy source in Saudi Arabia due to its high adaptability to harsh weather, saline water, desert, and hot temperature. In the present study, cold-pressed jojoba oil is used for the synthesis of biodiesel. In addition to that, this research work carried out a detailed optimization study of process parameters using response surface methodology. An empirical model is developed and employed for the optimization of process parameters. The study also investigates the significance of process parameters on biodiesel yield from the jojoba seed. Results show that the molar ratio of methanol to oil is the most significant input parameter, followed by the reaction time and NaOH concentration. The developed model was further validated using experimental results. The study also examined the combined effects of process parameters on process optimization. The maximum yield conditions are 15.99 molar ratio of methanol to jojoba oil, 15-min reaction time, and 1.5 wt% NaOH concentration.

霍霍巴种子因其对恶劣天气，盐水，沙漠和高温的高度适应性而成为沙特阿拉伯有吸引力的替代能源。在本研究中，冷压霍霍巴油用于生物柴油的合成。除此之外，这项研究工作还使用响应曲面方法对工艺参数进行了详细的优化研究。建立了经验模型，并将其用于过程参数的优化。该研究还研究了工艺参数对霍霍巴种子生物柴油产量的重要性。结果表明，甲醇与油的摩尔比是最重要的输入参数，其次是反应时间和NaOH浓度。使用实验结果进一步验证了开发的模型。该研究还检查了工艺参数对工艺优化的综合影响。最大产率条件是甲醇与霍霍巴油的摩尔比为15.99，反应时间为15分钟，NaOH浓度为1.5 wt％。
