以高游离脂肪酸含量的油脂为原料，采用非均相离子交换树脂为催化剂，建立了一种简单的连续化生产生物柴油-脂肪酸酯的工艺。在该系统中，填充有用于FFA酯化的阳离子交换树脂催化剂的膨胀床反应器和填充有用于甘油三酯酯交换的阴离子交换树脂催化剂的膨胀床反应器串联连接。当米糠毛油与14wt%FFA和乙醇的混合溶液被供给到所提出的系统时，脂肪酸酯的转化率可高达98.6%以上，而无需任何额外的操作，如原料油的脱蜡/脱胶，去除副产物，和添加醇。
A simple continuous production process of biodiesel fuel, fatty acid esters from oils with high content of free fatty acid (FFA), was constructed using the heterogeneous ion-exchange resin catalysts. In the system, the expanded-bed reactor packed with the cation-exchange resin catalyst for esterification of the FFA and that with the anion-exchange resin catalyst for transesterification of the triglyceride were connected in series. When the mixed solution of the crude rice bran oil with a 14 wt % FFA and alcohol was supplied to the proposed system, the fatty acid esters with a high conversion of more than 98.6% could be continuously produced without any extra operation such as dewaxing/degumming of the raw oil, removal of the byproduct, and addition of alcohol.
