加氢尾油非临氢降凝动力学模型

Kinetic Model of Non-Hydrogen Dewaxing of the Hydrotreated Tail Oil

结合加氢尾油催化裂解反应体系,利用集总的方法,建立了加氢尾油非临氢降凝五集总动力学模型。以催化降凝装置上得到的实验数据为根据,用Marquardt++算法编写Matlab语言程序进行优化计算,得到了加氢尾油非临氢的反应速率常数、指前因子和活化能。结果表明:该模型对原料和反应条件变化有较好的适应性,能较好预测不同条件下的产率分布和产品组成。

Based on the intensive investigations on the catalytic cracking reactions for hydro- treated tail oil residue, a 5- lump reaction network and its kinetic model have been established. Based on experimental data obtained from catalytic dewaxing equipment, a computational program was written by Marquardt^＋＋ method and Matlab language; and activation energy, reaction rate constant and preexponential factors were calculated. It turns out that the model fits well with raw materials and reaction conditions change, and product distributions and their yields are predicted well under different conditions.
