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。
