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.

The layer of solid KCl is so thin in depth、so small in size、 and so low in grade that it is too difficult to exploite it. Besides that, only 1/3 of the liquid KCl can be expoi ted due to the mining method of well and canal drainage which is being used now. Therefore, it is one of the key problems to exploite the liquid KCl as possible as we can and to turn the solid KCl into explo itable liquid deposit in Qarhan salt lake. So the idea of dissolving and driving exploitation has been suggested. This paper will deal with three problems as follow
