Abstract

Abstract: An exhaustive review of the scientific literature on kinetic modeling of heavy oil hydrocracking is reported in this paper, including traditional lumping (models based on wide distillation range fractions and models based on pseudocomponents), models based on continuous mixtures and models based on molecular level (structure oriented lumping and single event models).Reaction networks, main characteristics of kinetic approaches and kinetic parameter values are also reported.In the base of comparing the advantages of these models, the paper predicts the probably trend of this kind of hydrocracking models in the future:because of the complexity of heavy oil, traditional lumping methods will be important for the long time, however, for higher requirements of adaptation of the model, in the future, kinetic models of heavy oil hydrocracking are trending for more and more accurate,as a result, models based on continuous mixtures and models based on molecular level are attaching more and more people's attention.

摘要： 对近年来重油加氢裂化过程的动力学模型进行了归纳和总结，包括传统集总动力学模型（宽馏分集总模型以及离散型集总模型），基于连续混合物的集总动力学模型以及基于分子水平的动力学模型（结构导向和单事件模型）；对各模型中所用的反应网络、计算方法等方面做了详细的阐述和说明，并分析了各个模型的优缺点，就重质油加氢裂化过程的动力学研究来说，传统集总方法因其对原料产物的简化在今后的很长一段时间内将会一直是研究的重点，然而展望该方面的动力学模型研究，精确化与细致化必将是今后的发展趋势，基于连续混合物的集总模型以及基于分子水平的动力学研究会是今后研究的重点。
