Abstract: Naphtha is the main feedstock for ethylene production. Hence the modeling and simulation of naphtha cracking is important for making good use of naphtha. Simulation models for naphtha cracking can be divided as experience-based model，molecular reaction model and radical model. Advantages and disadvantages of these three models are discussed and their application is introduced. Special emphasis is given in the research progress for overcoming the difficulty in establishing molecular reaction model and radical model，their application and future research prospects are discussed.
