摘要: 用等温积分反应器,在与工业生产相似的条件下,研究了银催化剂上乙烯氧化制环氧乙烷本征反应动力学,得到了能反映该系统反应特性的速率方程.建立了乙烯氧化制环氧乙烷环柱状银催化剂内复合反应-传质-传热耦合过程二维数学模型。

Abstract: In this paper,the intrinsic kinetics of ethylene oxidation to ethylene oxide was studied in a constant temperature integral reactor under conditions similar to industrial production.The intrinsic rate equations were obtained.The two-dimension mathematical model of multiple reactions-mass transferheat transfer coupling process in hollow cylinder silver catalyst was set up.No assumption was made in this model.All parameters were obtained by experiments.
