Abstract:Hydrocracking is a key technology in the refining and petrochemical industry. With the help of reaction kinetics modeling and simulation techniques to understand hydrocracking mechanisms and to guide production,optimize plant operation can bring significant economic benefits could be achieved. This paper focuses on the use of lump method to study the relevant researches on hydrocracking reaction kinetics,including the kinetics models based on lumped by production method classification,discrete lumped and continuous lumped,describes the modeling method and development situation of these three kinds of lumped models,and presents the advantages and disadvantages of corresponding reaction networks. Comparison and analysis of the lumped models will provide a reference for modeling of hydrocracking. The continuous lumped model can take the properties of mixture and reaction pathways as well as changes of cutting schemes into consideration, then realize simulation of the complicated system hydrocracking reactor,and accurately predict distribution and properties of products. Meanwhile,further research direction of hydrocracking reaction kinetics modeling is also pointed out. Combining lump modeling and molecular modeling and developing a comprehensive mixed kinetic model will be a meaningful and challenging work in hydrocracking reactor simulation.
