Research Progress and Application of Steam Cracking Kinetic Model
摘要
Abstract
The research progress of kinetic modeling of steam cracking to light olefins in recent years is reviewed.Empirical models have been developed very maturely over the years,but they are limited to empirical parameters.Their accuracy and adaptability are still inadequate,and building the model is a significant undertaking.Recently,the scope of application of empirical models has been broadened by combining them with the developing technology of artificial intelligence.Molecular models treat light feedstocks based on average molecular composition,while heavy and complex feedstocks can be treated by molecular reconstruction.However,establishing this model still requires a substantial amount of experimental and industrial data.The free radical mechanism model is relatively well developed and can be established by the recently developed artificial intelligence,which can also be used to develop some cracking additives for reducing the plant's energy consumption and improving the yield of light olefins.Finally,an analysis of their current industrial applications and future development directions is conducted.The three existing steam cracking kinetic models each possess distinct advantages:the radical mechanism model is more widely applied to light hydrocarbon feedstocks,while empirical and molecular models are more prevalent for heavy hydrocarbon feedstocks.Future efforts will focus on refining the radical mechanism model and integrating empirical,molecular,and radical mechanism models to develop novel cracking kinetic models.关键词
