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是由多步可逆反应组成,从三甘酯到二甘酯,再到单甘酯和甘油,理论上一分子甘油酯完全酯交换可以得到三分子脂肪酸甲酯,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的进行速度,但反应的可预测性往往随条件的改变而改变。从工业连续化生产出发,建立合理的数学模型是非常必要的,提供一种基于动力学特征的有限微分模型,并从能量角度说明影响酯化反应的各种因素和条件控制。

Study on the differential kinetic model of transforming into biodiesel

Fat and oil transforming into biodiesel is consist of multistep reactions which is reversible,and from triglyceride into diglyceride,into monoglyceride again,into glycerol last.Theoretically,per molecular can get three molecular methyl ester if transesterificate whole,and result lie on reversible degree in fact.Catalyst and temperature could change the rate of the reaction,which couldn't predict production.View of continuous producing in industry, building reasonable math modeling is necessary.In this paper...
