| 摘 要： | 采用玻璃鼓泡反应器,进行石蜡催化氧化反应的实验,考察了反应时间和温度对石蜡催化氧化反应的影响。将石蜡催化氧化反应过程分为氧化反应阶段和酯化反应阶段,在此基础上建立了石蜡催化氧化反应动力学模型。实验结果表明,利用皂化值为参数建立的动力学模型可较好地表征石蜡催化氧化反应动力学过程;由150,160,170℃下的实验数据回归得到氧化反应阶段的表观活化能为41.653kJ/mol,指数前因子为48022.7h-1;酯化反应阶段的表观活化能为12.970kJ/mol,指数前因子为5.401h-1。

| Abstract: | Catalytic oxidation of paraffin wax was carried out in a glass bubbling reactor. Effects of reaction time and temperature on the reaction were investigated. The catalytic oxidation was assumed to be carried out in two stages: oxidation and esterification. Kinetics equations of catalytic oxidation of paraffin wax were established on basis of this assumption. Kinetics equations using saponification value as parameter can better characterize the process of paraffin wax oxidation. Parameters of the kinetic equa... |
