Abstract: Simulation computation shows that the performance of a flow reversal reactor depends weakly on the heat transfer parameters but strongly on the global kinetic parameters involved in its transient model. Based on fitting the model prediction of operation performance with the results obtained in bench - scale test, the global kinetic parameters in observed reaction rate equation are modified.Performance prediction and parameter analysis of one - stage flow reversal reactor for SO2 oxidation reaction are completed by using the transient heterogeneous model developed and the parameters modified. Recommendations for designing, operating and optimizing this reactor configuration are given.

摘要： 模拟计算证明,反应器操作特性对传热参数的变化是不敏感的,但对化学反应宏观动力学参数的变化是敏感的.通过使模型预测结果与大量模试数据相拟合的办法修正了宏观动力学参数.利用所发展的数学模型和修正后的参数,对单级反应器的操作性能进行了预测与分析,所得到的结论对工业反应器的设计、运行和优化具有指导作用.
