对固体碱催化剂催化固定床法工业化生产生物柴油进行了模拟．顺利进行了小试实验，并建立了生物柴油合成的酯交换反应的动力学模型，该模型能较为准确地描述酯交换反应．通过对文献中的气液平衡数据的回归得到了生物柴油的安托因方程．选择NRTL模型对脂肪酸甲酯（ FAME）甲醇甘油体系进行描述，得到了体系NRTL的二组分参数，利用Aspen Plus对该体系液液平衡数据（ LLE ）的回归得到了三组分相图．为了预测固定床工艺生产在工业规模放大1000倍后的效果， Aspen Plus对2个流程进行了仿真模拟，预测物料和能量消耗．模拟结果表明，与先前文献报道的数据相比，每小时生产每吨生物柴油至少可以减少350．42 kW的能量消耗．

Biodiesel industrial production based on a solid base catalyst in a fixed-bed was simulated.The lab and bench scale experiments were carried out effectively in which the kinetic model is established and it can describe the transesterification reaction well.The Antoine equation of biodiesel is regressed with the vapor-liquid data cited of literature.The non-random two liquid NRTL model is applied to describe the system of fatty acid methyl ester FAME methanol and glycerol and parameters are obtained.The Ternary phase map is obtained from Aspen Plus via the liquid-liquid equilibrium LLE data. In order to describe the production in a fixed-bed performs in industrial scale after being magnified 1 000 times the Aspen Plus simulation is employed where two flowsheets are simulated to predict material and energy consumption.The simulation results prove that at least 350.42 kW energy consumption can be reduced per hour to produce per ton biodiesel compared with data reported in previous references.
