Hydrocracking technology has played an important role in petrochemical industry.In order to deeply investigate the laws of hydrocracking reaction,optimize the process operating conditions and products distribution of industrial installation,and achieve the goal of petrochemical enterprises intellectualization and interest maximization,the research of hydrocracking reaction kinetics model has received wide attention.In this paper,the related research and application progress of hydrocrack-ing reaction kinetics models were reviewed,and the research history of hydrocracking reaction kinetics model was introduced.The objectives of hydrocracking reaction kinetics model research had developed from simple macroscopic correlation models in early phase to traditional and continuous lumping models which lumps were divided by fraction or other product programs,then the objectives had developed to be complex microscopic molecular lumping models.Application conditions of different hydrocracking reaction kinetic models were summarized; industrial practicability of traditional lumped model and raw mate-rials & products applicability of molecular lumping models were highlighted.It was pointed out that it is great significance and challenge to develop a comprehensive hybrid kinetic model combining with correlation models and lumping models (especi-ally molecular lumping) effectively in the research of hydrocracking and other petroleum processing reaction kinetic models in the future.
Key words: hydrocracking; kinetic model; correlation model; lumping model; molecular lumping
