摘　　要：采用等体积浸渍法制备了K2CO3/NaX固体碱催化剂,用于催化酯交换反应制备甲酯生物柴油。通过正交试验方法确定了最佳反应条件为:反应时间3 h、反应温度60℃、催化剂用量4%和醇油摩尔比14。在此反应条件下生物柴油的转化率可达87.5%。The solid base catalyst K2CO3/NaX was prepared by isovolumetric impregnation, and methyl ester biodiesel was prepared by transesterification with this catalyst. The optimal reaction conditions were analyzed by orthogonal experiment. And the optimal reaction conditions were as follows： reaction time 3 h, reaction temperature 60℃, catalyst rate 4 %, molar ratio of methanol to oil 14, the conversion ofbiodiesel under these conditions reached 87.5 %.
