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.
