Abstract

Abstract: Modeling of heat and mass transfer in fixed‐bed reactors for heterogeneously catalyzed gas phase reactions is possible using different methods. Homogeneous and heterogeneous continuum models as well as particle resolved modeling of fixed‐bed reactors show high potential for application. Considering those approaches, advantages and disadvantages as well as underlying assumptions and boundary conditions are discussed. Additionally, methods for experimental validation are presented and discussed focusing on the two‐dimensional homogeneous models. Abstract : Fixed‐bed reactors are commonly used for homogeneous catalyzed gas phase reactions. Therefore, methods for modelling fixed bed reactors and the respective advantages and disadvantages are presented and the possibilities for experimental validation are discussed. The focus lies on two‐dimensional, homogeneous continuum models.
