The research status of the catalysis and catalysis lump reaction kinetic model in the refining industry is expounded. The principles of lumped partition, establishment of reaction network, establishment of mathematical model, establishment of mathematic model, verification of model and application of dynamic model in optimization of operating conditions and reactor simulation are introduced in detail. Finally, the reaction kinetic model of the refining industry is prospected through the analysis of kinetic models of steam cracking, catalytic reforming, hydrocracking and delayed coking reaction. It is pointed out that the lumped reaction kinetic model has some limitations. The molecular level The reaction kinetic model can be based on the reaction mechanism to study the impact of various factors on the chemical reaction rate.
