查询词典 kinetic theory

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 calculation mechanics model is used for the curtain wall decussate rope net structure, including m horizontal ropes and n vertical ropes.
