| 摘 要： | 为解决生物柴油酯交换过程中的产物与催化剂分离问题，制备了负载型固体碱催化剂（CaO/SiO2、CaO/Al2O3和CaO/MgO体系），考察该系列催化剂在生物柴油制备中的不同反应特点，对制备的催化剂进行XRD表征，研究了反应条件对反应的影响。结果表明,CaO可以很好地分散在催化剂载体上，该体系催化剂是制备生物柴油的良好非均相催化剂。催化剂的最佳制备条件为：焙烧温度700 ℃，催化剂质量分数为原料油的1%，m（醇）∶m（油）＝18∶1，反应温度60～65 ℃，反应时间10 h。

| Abstract: | Heterogeneous solid base catalysts (CaO based catalysts), such as CaO/SiO2, CaO/Al2O3 and CaO/MgO, were prepared and used in transesterification reaction for production of biodiesel. The catalysts were characterized by XRD and BET. Influences of transesterification condition were investigated. The results showed that CaO was well dispersed over the support and the supported CaO catalysts exhibited excellent activity for the transesterification. Optimal conditions for catalyst preparation and transesterification reaction are as follows: calcination temperature 700 ℃，catalyst dosage=1% of the oil,n(methanol)∶n(oil)=18∶1, reaction temperature 60-65 ℃，reaction time 10 h. |
