Thinking of presenting problems, this research mainly studied some solid base catalysts which own higher catalysis ability and longer lifetime. Then, the phase diagram and equilibrium data of oil-alcohol-biodiesel-glycerol multiphase system were measured because the biodiesel producing process lacks of thermodynamic data.Based on a double-membranes theory and the thermodynamic data, a kinetic model was proposed. In addition, a mult-step extraction process was proposed to dispose the jatropha curcas l oil with high acid value in order to decrease the acid value. Then, a new technology of biodiesel producing using solid base as a catalyst was developed. The study objects and results are as follows.

本研究针对负载型固体碱催化剂活性组分易流失、使用寿命短的缺点，制备了高效、稳定的固体碱催化剂；针对生物柴油制备体系热力学数据缺乏的问题，测定了大豆油-醇-生物柴油-甘油体系的相图和平衡特性，在此基础上基于双膜理论，建立了固体碱制备生物柴油的动力学模型；同时针对酸价较高的麻疯果油，提出了先用甲醇或乙醇多级萃取降低酸价，再用固体碱催化制备的新工艺。

The phase equilibrium data of SBO-FAME-Methanol, SBO-FAEE-Ethanol and Glycerol-FAEE-Ethanol systems were measured. The results indicated that it involved two different stages: liquid-liquid-solid reaction stage and liquid-solid reaction stage. When the molar ratio of methanol to oil is 12:1 at 65℃, the turning point is at a 55% biodiesel yield. The liquid-liquid-solid reaction model was proposed based on the double-membranes theory. It indicated that the process is reaction and mass transfer controlled together at the first stage, and the second stage is reaction controlled. The predictions of the model are matched with the experimental results.In the end, the acid was extracted using methanol and ethanol from jatropha curcas l oil.

测定了生物柴油制备过程中的SBO-FAME-Methanol、SBO-FAEE-Ethanol、Glycerol-FAEE-Ethanol三组分相平衡数据，表明固体碱催化过程分为液-液-固和液-固两个反应阶段，在醇油摩尔比为12：1、65℃的初始反应条件下，转化率达到55%时，为第一阶段向第二阶段的转折点；基于双膜理论建立了固体碱催化制备生物柴油的非均相液-液-固反应模型，表明两个反应阶段分别为传质、反应共同控制和反应控制，模型计算值与实验值吻合较好。
