| 摘 要： | 分析了现有4种蒸汽热裂解动力学模型的优缺点和局限性,同时介绍了利用分子模拟手段进行的分子尺度动力学模型的研究进展.通过对上述文献的分析、总结,提出了对今后裂解动力学研究方法的一些看法,认为应建立具有一定外推性和有一定准确度预测性的动力学模型,充分考虑不同分子结构的烃类在裂解自由基反应过程中动力学规律的不同,进一步完善目前已建立的模型及所用的数学手段,对复杂原料的实验研究应将分子模拟得到的预测结果通过理论分析得到的新观点进行实验.

| Abstract: | Analyzed the advantages,disadvantages and limitations of the existing four kinds of kinetics model of steam pyrolysis,also introduced the research progress on dynamical model of molecular size by molecular simulation method.Through analyzing and summarizing the above literatures,proposed some views on research method of future pyrolysis kinetics.The predictive kinetic model with extrapolation and accuracy should be built,the different dynamic law in cracking reaction with different molecular structure should be thoroughly considered,further improved the established model and mathematical means should be used,Experimental research on complex raw materials should experimented to prove the new point obtained from the theoretic analysis of forecasting results used molecular simulation. |
