It is shown that the KF/γ-Al₂O₃ catalyst obtained by the sol–gel method has a greater activity in the process of transesterification of methanol and rapeseed oil to biodiesel compared to KF/γ-Al₂O₃ prepared by impregnation. The highest yield of biodiesel (96.5%) is achieved with use of KF/γ-Al₂O₃, prepared at molar ratio KF to γ-Al₂O₃ 1.3:1. High conversion of rapeseed oil to biodiesel is explained by the relatively high basicity and specific surface of KF/γ-Al₂O₃.

在 KF/γ-Al2O3 催化剂上将菜籽油转化为生物柴油

结果表明，与浸渍法制备的KF/γ-Al ₂ O _{3相比，溶胶-凝胶法制得的KF/γ-Al 2} O ₃催化剂在甲醇和菜籽油酯交换制生物柴油过程中具有更高的活性。. _{使用以 KF 与 γ-Al 2} O ₃摩尔比为1.3:1制备的 KF/γ-Al ₂ O ₃可获得最高的生物柴油产率 (96.5%) 。_{KF/γ-Al 2} O ₃相对较高的碱度和比表面积解释了菜籽油向生物柴油的高转化率。
