This study optimized biodiesel synthesis from Pangasius fat using a Box-Behnken experimental design. The manipulation of key variables included the CoFeO catalyst dosage, the methanol-to-fat molar ratio, and the ultrasonic wave amplitude. We determined optimal conditions for biodiesel synthesis through the central runs, resulting in a remarkable 96.5% yield. The produced biodiesel exhibited diverse fatty acid compositions and met specifications for viscosity, specific gravity, acid value, and iodine value. Furthermore, we conducted a comprehensive life cycle assessment (LCA) to shed light on the environmental implications of the process. The LCA revealed a minimal global warming potential of 0.21 kg CO per kg of biodiesel produced, demonstrating the environmental viability of the entire process. These significant findings highlight the promising potential of using fat as a sustainable feedstock for biodiesel production. Additionally, they provide valuable insights into developing ecologically friendly energy sources.
本研究采用Box-Behnken实验设计优化了从巴沙鱼脂肪中合成生物柴油的过程。关键变量的控制包括CoFeO催化剂用量、甲醇与脂肪的摩尔比以及超声波振幅。我们通过中心试验确定了生物柴油合成的最佳条件，产率高达96.5%。所生产的生物柴油具有多种脂肪酸组成，并且符合粘度、比重、酸值和碘值的规格要求。此外，我们进行了全面的生命周期评估（LCA），以阐明该过程对环境的影响。生命周期评估显示，每生产1千克生物柴油的全球变暖潜能值极低，仅为0.21千克二氧化碳，这证明了整个过程在环境方面的可行性。这些重要发现凸显了将脂肪用作生物柴油生产可持续原料的巨大潜力。此外，它们为开发生态友好型能源提供了有价值的见解。
