The production of biodiesel from refined sunflower vegetable oil over basic CaO/ZSM-5 catalysts was investigated. Several catalysts with various loadings of CaO on ZSM-5 were prepared, calcined at 800 °C, and characterized by N2 adsorption-desorption, X-ray diffraction, Fourier transform infrared spectroscopy, and CO2-temperature-programmed desorption techniques. Calcined catalysts were tested in the transesterification reaction and reaction conditions were optimized by varying the catalyst-to-oil ratio and reaction time. The most active catalyst was the CaO/ZSM-5 catalyst with a 35 wt % loading which gave the highest fatty acid methyl ester yield. The high catalytic activity was attributed to the active basic sites generated following CaO addition. Furthermore, the catalyst demonstrated stability against the leaching process.

使用 CaO/ZSM-5 粉末催化剂将精制葵花籽油酯交换为生物柴油
研究了在碱性 CaO/ZSM-5 催化剂上从精制向日葵植物油生产生物柴油。在 ZSM-5 上制备了几种不同负载量的 CaO 催化剂，在 800 °C 下煅烧，并通过 N 2吸附-解吸、X 射线衍射、傅里叶变换红外光谱和 CO 2表征-程序升温解吸技术。在酯交换反应中测试了煅烧的催化剂，并通过改变催化剂与油的比例和反应时间来优化反应条件。最活性的催化剂是 CaO/ZSM-5 催化剂，负载量为 35%（重量），脂肪酸甲酯产率最高。高催化活性归因于添加 CaO 后产生的活性碱性位点。此外，该催化剂表现出对浸出过程的稳定性。
