摘　　要：基于高温热裂解β-蒎烯生产月桂烯工艺,建立反应核心装置-裂解反应器的动力学模型,并基于g PROMS建模平台,利用不同工况的工业运行数据对模型动力学参数进行估计,进而构建β-蒎烯热裂解反应过程模型。模型验证结果表明,模型对月桂烯产品浓度具有较好的预测性能。同时,模拟分析了进料流量、操作压力和反应温度等参数对月桂烯产品浓度的影响,较佳的工艺条件是蒎烯进料流量为210 L/h,操作压力为0.09 bar,反应温度为510℃,为生产操作条件的优化、负荷的调整以及过程安全平稳生产的运行提供重要参考。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.
