摘　　要：以元宝枫油为原料,研究了元宝枫油在提取神经酸同时制备生物柴油的最优技术条件。预酯化工艺参数为:原料油与乙醇摩尔比1∶6,酯化时间2.5 h,催化剂用量4.0%;酯交换工艺参数为:预酯化混合物与乙醇摩尔比1∶6,催化剂用量1.0%,酯化时间3 h;分子蒸馏工艺参数为:初级分子蒸馏压力97 Pa,蒸馏温度60℃,物料流量1 kg/h;二级分子蒸馏压力50 Pa,蒸馏温度170℃,物料流量1 kg/h;三级分子蒸馏压力10 Pa,蒸馏温度170℃,物料流量0.3 kg/h。两次放大试验所得到的产品神经酸含量达到47%左右,生物柴油质量达到了GB/T 20828—2007国家标准。Acer truncatum Bunge seed oil was used as raw material for producing nervonic acid and biodie- sel simultaneously. Pre -esterification parameters were： molar ratio of Acer truncatum Bunge seed oil to ethanol 1 ： 6, reaction time 2.5 h, dosage of catalyst 4.0%. Transesterification parameters were ： molar ratio of pre- esterification mixtures to ethanol 1 ： 6, reaction time 3 h, dosage of catalyst 1.0%. Molecular distillation parameters were ： the first molecular distillation pressure 97 Pa, temperature 60℃, materi- al flowing rate 1 kg/h; the second molecular distillation pressure 50 Pa, temperature 170℃, material flowing rate 1 kg/h;the third molecular distillation pressure 10 Pa, temperature 170 ℃, material flowing rate 0.3 kg/h. The content of nervonic acid in the product obtained by pilot plant tests was about 47%, and the quality of biodiesel reached national standard GB/T 20828--2007.
