摘要
1 模拟计算1.1 动力学和流动模型模拟计算中采用陈纪忠等建立的动力学模型,其反应网络为:描述该6种组分的生成或消失速率的动力学方程式在文献[1]中已有详细报道。从冷模研究得到:液相流动为全混流;u_g≥7 cm/s 时气相流况可视作平推流。若从各种流动模型的计算结果看,气相即使作为全混流,计算结果差异也甚小。本文采用液相全混、气相平推的流动模型。
This paper deals with the model calculation and the modification of kinetics of autocatalytic oxidation of cyclohexane.The calculated results indicated that conversions and yields calculated by equations(C)of the modified kinetics are more consistent with the data obtained from industrial plant and that the initial concentration of cyclohexanone in feed can affect the course of reaction and the distribution of final products significantly.
