A novel method based on cup-mixing concentration and superficial velocity is presented for the analysis of reactions in isothermal fixed-bed reactors. It is founded on experimentally observed profiles of concentration and velocity so as to preserve the heterogeneity of a reaction system. The domain of application of the model includes reaction systems at lower Reynolds numbers and Péclet numbers of less than 700 with a void fraction of for which the ratio of the bed-length-to-particle diameter to particle Péclet number exceeds .

多孔介质反应的新观点和模型

提出了一种基于混杯浓度和表观速度的新方法，用于分析等温固定床反应器中的反应。它基于实验观察到的浓度和速度曲线，以保持反应系统的异质性。该模型的应用领域包括较低雷诺数和小于 700 的 Péclet 数的反应系统，其中床长与颗粒直径与颗粒 Péclet 数之比超过.
