Abstract

This research explores the synthesis and characterization of biodiesel derived from Moringa oleifera oil, specifically focusing on the effects of ethanol blending on its fuel properties. Utilizing M. oleifera, known for its high fatty acid content and oxidative stability, this study evaluates the production of M. oleifera biodiesel (MB) and the physicochemical properties of M. oleifera biodiesel—blended ethanol. The methodology encompasses thorough experimental procedures, from oil extraction to biodiesel production, including treatment steps like degumming, neutralization, and transesterification. Advanced mathematical modeling techniques, such as the Jouyban–Acree model, are employed to analyze the impacts of ethanol blending on key properties like viscosity and density. Ethanol blending significantly modifies these properties, with improvements of approximately 10% in viscosity and 8% in density, potentially allowing the fuel to meet or exceed conventional diesel standards. Thereby supporting the adoption of MB blends in energy applications for reduced environmental impact.

辣木生物柴油和乙醇混合物的评价：对燃料特性的影响和数学建模

本研究探索了从辣木油中提取的生物柴油的合成和表征，特别关注了乙醇混合对其燃料性能的影响。本研究利用油橄榄这种脂肪酸含量高、氧化稳定性好的植物，对油橄榄生物柴油（MB）的生产以及油橄榄生物柴油-混合乙醇的理化性质进行了评价。该方法包括彻底的实验程序，从油提取到生物柴油生产，包括脱胶、中和和酯交换等处理步骤。先进的数学建模技术，如Jouyban-Acree模型，被用于分析乙醇混合对粘度和密度等关键性能的影响。混合乙醇显著改变了这些特性，粘度提高了约10%，密度提高了8%，有可能使燃料达到或超过传统柴油标准。从而支持在能源应用中采用MB混合物，以减少对环境的影响。
