生物柴油转化微分动力学模型研究

动植物油脂转化为生物柴油的过程是由多步可逆反应组成的.理论上1分子甘油酯完全酯交换可以得到3分子脂肪酸甲酯,但实际情况取决于反应的可逆程度.催化剂和反应温度可以改变反应速度,但反应的可预测性往往随反应条件的改变而改变.建立合理的数学模型对工业化连续生产生物柴油是非常必要的.文章提供了一种基于动力学特征的有限微分模型,从能量角度说明影响酯化反应的各种因素和控制条件.

Study on the differential kinetic models for transforming preparation

Fat and oil transforming into biodiesel process is consist of multi-step reactions which are reversible,and from triglyceride into diglyceride,into monoglyceride again,and into glycerol at last.Theoretically,per molecular can get three molecular methyl ester if transesterificate wholely,but the result lies on the reversible degree in fact.The catalyst and the temperature could change the rate of the reaction,but the production couldn't be predicted.In the view of continuous producing in industry,building re...
