The synthesis of fatty acid methyl ester (FAME) from the high- and low-acid-content feedstock of crude palm oil (CPO) and karanj oil (KO) was conducted over CaO-La2O3-Al2O3 mixed-oxide catalyst. Various reaction parameters were investigated using a batch reactor to identify the best reaction condition that results in the highest FAME yield for each type of oil. The transesterification of CPO resulted in a 97.81% FAME yield with the process conditions of 170°C reaction temperature, 15:1 DMC-to-CPO molar ratio, 180min reaction time, and 10wt.% catalyst loading. The transesterification of KO resulted in a 96.77% FAME yield with the conditions of 150°C reaction temperature, 9:1 DMC-to-KO molar ratio, 180min reaction time, and 5wt.% catalyst loading. The properties of both products met the ASTM D6751 and EN 14214 standard requirements. The above results showed that the CaO-La2O3-Al2O3 mixed-oxide catalyst was suitable for high- and low-acid-content vegetable oil.
用 CaO-La2O3-Al2O3 混合氧化物催化剂合成了高酸值和低酸值的棕榈油（CPO）和麻疯树油（KO）的脂肪酸甲酯（FAME）。在间歇式反应器中考察了各种反应参数，以确定每种油获得最高 FAME 产率的最佳反应条件。CPO 的酯交换反应在 170°C 的反应温度、15:1 的 DMC 与 CPO 的摩尔比、180min 的反应时间和 10wt.%的催化剂负载下得到了 97.81%的 FAME 产率。KO 的酯交换反应在 150°C 的反应温度、9:1 的 DMC 与 KO 的摩尔比、180min 的反应时间和 5wt.%的催化剂负载下得到了 96.77%的 FAME 产率。这两种产物的性能均符合 ASTM D6751 和 EN 14214 标准要求。上述结果表明，CaO-La2O3-Al2O3 混合氧化物催化剂适用于高酸值和低酸值的植物油。
