By means of utilizing sunflower oil and Jatropha oil as raw oil respectively, the biodiesel transesterification production and the multi-stage extracting separation were carried out experimentally. Results indicate that dealcoholized crude glycerol can be utilized as the extracting agent to achieve effective separation of methanol from the methyl ester phase, and the glycerol content in the dealcoholized methyl esters is as low as 0.02 wt.%. For the biodiesel separation process utilizing glycerol extracting dealcoholization, its technical and equipment information were acquired through the rigorous process simulation in contrast to the traditional biodiesel distillation separation process, and results show that its energy consumption decrease about 35% in contrast to that of the distillation separation process. The glycerol extracting dealcoholization has sufficient feasibility and superiority for the biodiesel separation process.
分别利用葵花籽油和麻疯树油作为原料油，进行了生物柴油酯交换生产和多阶段萃取分离实验。结果表明，经脱醇后的粗甘油可用作萃取剂，从甲酯相中有效分离甲醇，且脱醇甲酯中的甘油含量低至 0.02wt.%。对于利用甘油萃取脱醇的生物柴油分离工艺，通过与传统的生物柴油蒸馏分离工艺的严格过程模拟，获得了其技术和设备信息，结果表明，与蒸馏分离工艺相比，其能耗降低了约 35%。甘油萃取脱醇对于生物柴油分离工艺具有足够的可行性和优越性。
