Abstract: Abstract：In today’s petroleum industry, the optimization of raw materials for ethylene production has become very important. In China, alternatives to naphtha as ethylene cracker feedstock have been studied. Some of the secondary processing oil, such as topped oil is a good raw material for producing ethylene because of its good characteristics, and it is now used more often in practice. Some research on reaction kinetics of topped oil was done and a new model for topped oil pyrolysis was presented and used to simulate the topped oil pyrolysis experiment in Lanzhou Petrochemical Research Institute . The simulation results agreed well with experimental data. Our work provides the basis for further study of topped oil pyrolysis model and numerical simulation.

摘要： 摘 要：针对拔头油热裂解的反应动力学进行了研究，结合前人经验构造一个新的分子反应动力学模型，并将新模型应用于针对石化研究院的拔头油热裂解制乙烯标定实验的模拟，模拟结果与实验结果相符合，新模型能较好地反映实验室热裂解过程。为进一步研究工业拔头油热裂解的分子反应动力学模型提供了基础，能更好地对拔头油热裂解过程实现数值模拟。
