生物燃料被认为是生态友好、可生物降解、无毒和碳中性的燃料。它由食用或非食用油原料制成，包括其他甘油三酯来源。生物柴油的生产取决于特定原料的可用性和所需原材料的成本。生物柴油主要通过使用合适的催化剂优选多相催化剂的酯交换法生产，因为它在可重复使用性、回收率、产品纯度和生产成本方面也更有利。开发了各种反应器以在商业水平上生产具有成本效益的生物柴油。生物柴油合成的最新趋势是应用机器学习（ML）技术来优化工艺参数。两种或两种以上油脂的混合物作为生物柴油合成的原料（非食用油或食用油）的应用受到重视，并且目前变得越来越重要。本文综述了各种混合油（混合油）制备生物柴油的研究进展，并讨论了混合油对生物柴油的反应、理化性质、脂肪酸组成和燃料品质的影响。研究结果表明，各种催化剂在混合油反应中的活性和经济可行性。结果表明，混合油的比例是影响生物柴油转化率和质量的重要因素。它还揭示了ML技术的应用是本质上有用的，以优化生产效率。混合油的利用将克服与原料不可用相关的问题，并降低生物柴油的总成本，同时提高生物柴油的质量。这种方法提高了大规模生产生物柴油的可能性，如果先进水平的研究朝着正确的方向发展，可能会促进生物炼制部门满足未来的能源需求。
Biodiesel is considered eco-friendly, biodegradable, non-toxic, and carbon-neutral fuel. It is made from edible or non-edible oil feedstocks including other triglyceride sources. The production of biodiesel depends on the availability of a particular feedstock and the cost of desired raw materials. Biodiesel is mainly produced by the transesterification process using a suitable catalyst preferably a heterogeneous catalyst as it is more beneficial in terms of reusability, recovery, product purity, and production cost as well. Various reactors are developed to produce cost-effective biodiesel at the commercial level. The latest trend in biodiesel synthesis is the application of the machine learning (ML) technique to optimize the process parameters. The application of a mixture of two or more oils as feedstock either non-edible or edible oil is emphasized for biodiesel synthesis and is presently getting more importance. In this paper, the production of biodiesel from various mixed oil (hybrid oil) is reviewed and the effects of mixed oil on the reaction, physicochemical properties, fatty acid composition, and fuel quality of the product are discussed. The study highlighted the activity of various catalysts in the reaction of mixed oil and the economic feasibility. It was found that the ratio of mixed oil is an important factor in terms of conversion and quality of biodiesel. It is also revealed that the application of the ML technique is essentially useful to optimize production efficiency. The utilization of mixed oils will overcome the issues related to the non-availability of feedstocks and reduce the overall cost with improved quality of biodiesel. This approach enhances the production possibility of biodiesel at a large-scale and may boost the biorefinery sector satisfying the future energy demand if the research at the advanced level goes in the right direction.
