Experimental and theoretical analysis of the hydrodynamic and reaction behavior of inclined rotating tubular fixed bed reactors for gas-liquid reactions

在过去对倾斜旋转固定床气液反应反应器的流体力学和反应行为进行了实验和理论分析的基础上，提出了一种新的反应器概念。特别地，对不断变化的流动形式进行了表征，并在分层流动条件下实验证明了转换的增强。后续项目旨在开发一种面向应用的预测模型方法，用于计算不同分层流倾斜旋转反应器设计的时空产率。该模型基于两相欧拉CFD模型，该模型预测了分层流的演化。催化剂填料的周期性润湿和排水的影响是通过一个链接的催化剂颗粒模型来解决的。整个模型的成功建立取决于对分层流的关键参数进行系统的实验分析，这些参数取决于反应器的转速、倾斜度和流体相的流速，以及填料规格和反应器设计。该模型将根据实验反应数据进行验证，随后用于确定合适的操作条件。本程序确保为旋转管式反应器的工艺设计提供所有必需的方法。

In the past project on the experimental and theoretical analysis on the hydrodynamic and reactive behavior of an inclined rotating fixed bed reactor for gas-liquid reaction, a new reactor concept was developed. In particular the evolving flow regimes were characterized and a conversion enhancement at stratified flow conditions was experimentally shown.The follow-up project aims on the development of an application-oriented and predictive model approach for the calculation of the space time yield for different inclined rotating reactor designs with stratified flow. The model is based on the two-phase Euler CFD model, which predicts the evolving stratified flow. The effects of the periodic wetting and draining of the catalyst packing is addressed by a linked catalyst particle model.The successful development of the whole model depends on a systematic experimental analysis of the key parameters of the stratified flow depending on reactor rotational velocity, inclination properties and flow rates of the fluid phases as well as on the packing specifications and reactor designs. The model will be validated against experimental reaction data and subsequently used for the identification of suitable operating conditions. This procedure ensures providing all required methods for the design of processes in rotating tubular reactors.
