浸没式膜反应器耦合多相催化反应与膜分离技术，具有广阔的应用前景，但是以流体力学模型为基础的浸没式膜反应器设计理论尚未建立，制约其高效设计、优化及应用。本项目以计算流体力学（CFD）模拟为研究方法，以苯酚加氢制环己酮为模型反应，针对1）膜反应器内多相流体的复杂流动机理和2）流动特性对膜反应器综合性能的影响机制这两个关键科学问题开展研究。主要研究内容包括：1）探索膜管的微结构参数、构型、数量及排布方式对膜反应器内流体力学性质的影响规律，获得均匀的流动状态；2）研究流动特性对传质过程、反应过程和膜分离过程的影响机制，建立流动-传质、流动-反应以及流动-膜分离之间的定量关系；3）探索流动特性对膜反应器综合性能的影响规律，构建催化反应与膜分离之间的匹配关系。本项目将获得浸没式膜反应器内流动特性及其影响的机理性认识，建立具有工程实用价值的模拟方法，为浸没式膜反应器的高效设计及优化提供理论指导。

Submerged membrane reactors coupling multiphase catalytic reactions with membrane separation have wide application prospects. However, the design theory based on hydrodynamic models has not been established for submerged membrane reactors, which limits the efficient design, optimization and applications of submerged membrane reactors. By computational fluid dynamics (CFD), this project focuses on two key scientific issues, i.e. the complex mechanisms of multiphase flows in submerged membrane reactors and the influence of hydrodynamics on the overall performance of submerged membrane reactors. Phenol hydrogenation to cyclohexanone is used as the model reaction. First, different flow behaviors in membrane reactors are studied by considering the micro-structure parameters of membranes, the membrane tube configurations, the number and arrangement of membrane tubes. The uniform flow pattern will be achieved. Second, the mass transfer process, catalytic reaction process and membrane separation process in membrane reactors will be investigated by considering the influence of hydrodynamics. The quantitative relations of hydrodynamics will be established for mass transfer process, catalytic reaction process and membrane separation process, respectively. Third, the overall performance of the submerged membrane reactor will be investigated by considering the influence of hydrodynamics. The match between catalytic reaction process and membrane separation process will be achieved. The project implementation would obtain fundamental insights on the hydrodynamics in submerged membrane reactors and its influence. The simulation method would be developed for engineering applications, and the theoretical guide would be provided for efficiently designing and optimizing the submerged membrane reactors.
