Abstract: A detail review of the scientific literature on kinetic modeling of vacuum gas oil (VGO) hydrocracking is presented in this paper. This review includes models based on the lumping technique, continuous mixtures, structure oriented lumping, and single event. The advantages and disadvantages of corresponding reaction networks are also reported. Meanwhile, the impact of kinetic parameters and other related experiment data on the accuracy for predicting detail product composition and product distribution based on experiment data and feed properties is described.
