英文摘要：

A kinetic model of high temperature cracking tubular reactor in industry was established base on the technology of production of myrcene by pyrolysis of β-pinene. Then, the kinetic parameters of this model were estimated by industrial data of different operating condition base on g PROMS modeling platform. Results of model validation showed that the model had a good prediction performance for the myrcene concentration. Simultaneously, the effect of feed flow rate, pressure and temperature in reactor on concentration of myrcene was simulated and analyzed. Thus the optimum technological parameters were obtained as following： the feed flow rate 210 L·mol-1, pressure 0.09 bar, and reaction temperature 510 ℃, which provided a reliable reference for the equipment operation optimization, load adjustment and the smooth operation.
