摘要
针对定态、等温、恒容、单股进料的复杂反应过程 ,首先将反应器网络综合可得区分区法由浓度空间拓展至瞬时选择性 关键反应物未转化率 (S x)空间 ,然后根据分区法中两条重要曲线的特性 (选择性最大曲线dS/dx=0 ,单程收率最大曲线S =0 )建立了以废料最少为目标的反应器网络基本组成单元 (PFR和CSTR)的数学模型 ,并以VandeVusse反应模式为例将其应用于由分区法确定的最优反应器网络结构的模拟计算 .计算结果与文献值一致 ,表明本文所用方法具有一定的简捷性和实用性 .
For the complex reactions (steady state, isothermal,constant volume and one inflow), this paper extends the attainable region partition method of reactor network synthesis from the concentration space to the instantaneous selectivity (S)-unreacted fraction of key reactant (x) space and establishes the models of two reactor networks basic constituent elements (PFR and CSTR) for waste minimization according to the properties of two important curves (maximum selectivity curve: dS/dx=0; maximum yield curve: S=0) within the partition method of reactor network synthesis and applies them to the simulation of the optimal reactor networks structure obtained by the partition method for several Van de Vusse reaction examples. The computation results are consistent with those reported in the literatures, which indicates the proposed method is to some extent convenient and practical.
