The present study was mainly focused on the production of biodiesel from Calophyllum inophyllum oil. The oil was characterized by GC-MS and stored for biodiesel production. The heterogeneous catalyst was synthesized for effective production of biodiesel. The synthesized catalyst was found to have good activity and stability. The surface and element characterization of zinc doped calcium oxide was characterized by SEM and EDAX. The size of nanocomposite was found to be in the range of 14.3-65.6 nm. The EDAX has confirmed the presence of zinc on the surface of the calcium oxide. The maximum biodiesel yield of 89.0% (v/v) was obtained at 55 °C in 80 min and catalyst concentration of 6% (w/v). The optimized methanol:oil molar ratio was obtained at 9:1 for the production of biodiesel. The produced methyl ester was confirmed by GC-MS analysis.
本研究主要集中在利用桐花油生产生物柴油。通过 GC-MS 对油进行了表征，并将其储存用于生物柴油生产。合成了多相催化剂以有效生产生物柴油。合成的催化剂表现出良好的活性和稳定性。通过 SEM 和 EDAX 对锌掺杂氧化钙的表面和元素特征进行了表征。纳米复合材料的尺寸范围为 14.3-65.6nm。EDAX 证实了锌在氧化钙表面的存在。在 55°C 下，催化剂浓度为 6%（w/v），反应 80 分钟，可获得 89.0%（v/v）的最大生物柴油产率。生产生物柴油的最佳甲醇：油摩尔比为 9:1。通过 GC-MS 分析确认了所生成的甲酯。
