Abstract：Ethylene is an important basic raw material for the petrochemical industry, and its production mainly relies on hydrocarbon steam cracking technology, while the kinetic model of the cracking reaction is the core for modeling the steam cracking process for ethylene production. This paper systematically summarized the research progress of hydrocarbon steam cracking reaction kinetics, including empirical model, molecular reaction kinetics model, free radical reaction mechanism model and data-driven model, and deeply analyzed the roles and performances of different models in the reaction mechanism and product distribution prediction. The empirical model has high computational efficiency but limited prediction accuracy and adaptive range; the molecular kinetics model has greatly improved prediction accuracy but limited extrapolation; the free radical reaction mechanism model has shown significant advantages in describing the complex reaction network and it can accurately predict the distribution of cracking products, which has become the main technical route for modeling cracking reaction kinetics at present; the data-driven model has advantages in both high efficiency and accuracy, but it needs to rely on a large amount of reliable data. Finally, this paper looked forward to the potential research direction of the kinetic models of hydrocarbon steam cracking reaction, focusing on the deep integration of reaction network automatic generation and artificial intelligence, in order to further improve the model's versatility and prediction accuracy, and to promote the optimization of ethylene cracking process and the development of smart manufacturing.
