用绝热反应器研究乙苯脱氢的宏观动力学

Research of Rcaction Kinetics of Ethylbenzene Dehydrogenation by Using an Adiabatic Reactor

在实验室绝热反应器中进行了乙苯脱氢制苯乙烯的反应动力学研究。根据不同反应机理，提出五种反应模型，经残差分析及模拟计算规律与实验规律的比较，确定Ｃａｒｒａ双曲模型为最佳反应动力学模型。通过对实验数据的回归拟合，经参数估计求得了速率方程的频率因子和活化能。

The research of ethylbenzene dehydrogenation kinetics has been carried out in an experimental adiabatic reactor.The carra model was confirmed to be the best by model discrimination,and tne values of model parameters were obtained by parameters estimation of the experimental data.
