摘　　要：为了改善柴油的燃烧性能以及减少尾气污染,要求柴油向低硫、低芳烃、低密度方向发展。开发优良的加氢脱芳烃催化剂对于油品质量升级和清洁燃料生产有着重要意义。芳烃加氢反应动力学研究的主要应用就是指导工艺优化、通过动力学参数的内在联系反映出催化剂的性能,为催化剂的研制提供依据,以及与反应器相结合,为反应器的设计开发提供理论依据。结合PA/MA的比例以及原料氮含量对指前因子的关联修正,建立了柴油加氢脱芳烃的集总反应动力学模型,并验证了模型参数和检验模型的合理性。建立的模型可以为不同操作条件下芳烃加氢反应的预测及工艺条件优化提供准确的理论计算数据,同时也可为指导新催化剂的研制提供一定的理论基础。In order to improve the performance of diesel combustion and reduce exhaust pollution, production of diesel fuel with low sulfur, low aromatic and low-density is the development direction. Development of an excellent dearomatization catalyst has the great significance for upgrading the quality of oil and clean fuel. The main application of aromatic hydrogenation reaction kinetics is to guide process optimization, to provide a basis for the development of the catalyst through internal relations of kinetic parameters reflecting the performance of the catalyst, and to provide the theoretical basis for the reactor design and development. In this paper, a diesel dearomatization lumping kinetic model was established combined with PA / MA ratio and nitrogen content of the raw material pre-exponential factor correction, and the reasonableness of the model parameters and test models was verified. This model can provide the accuracy theoretical calculation data to optimize the forecast and process conditions of aromatic hydrogenation reactions under different operating conditions,and also provide theoretical basis for guiding the development of new catalysts.
