中文摘要： 整体催化剂在气液固三相反应中的应用研究非常广泛，然而其中的三相传质与反应的匹配协调关系是困扰整体催化剂进一步发展的重要问题。本项目以蒽醌选择性加氢制过氧化氢为探针反应，在泰勒流动的操作条件下，系统深入研究整体催化剂单一孔道内气液传质特点、液固传质特点、催化反应特征，获得传质模型和催化反应动力学模型参数。借助于高效液相色谱(HPLC)，色质联用(GC-MS)等分析检测手段，揭示传质与反应的匹配关系对气液固三相反应的选择性、转化效率和催化剂的稳定性影响规律。建立传质与反应协同调控的数值模型，模拟整个整体催化剂通道内参与反应物的种类与浓度场分布特点。通过本项目的研究，实现整体催化剂上气液固三相催化反应过程的工艺优化调控，为整体反应器在气液固三相催化反应中设计以及优化控制策略提供理论指导。

英文摘要： Monolith catalyst has been extensively investigated in the field of gas-liquid-solid three-phase catalytic reaction. However, the matching relationship between mass transfer and chemical reaction has been ambiguous, which is an obstacle for the further development of monolith catalyst. With the selective hydrogenation of anthraquinone to produce hydrogen peroxide as an probe reaction, under the Taylor flow operating condition, the characteristics of gas-liquid mass transfer, liquid-solid mass transfer and catalytic chemical reaction in an channel of monolith catalyst will be researched in this present project. The model formula of mass transfer and reaction kinetics will be proposed. With the aid of analytical detection method such as High Performance Liquid Chromatography, Gas Chromatography-Mass Spectrometry, the effect of the matching relationship between mass transfer and chemical reaction on the selectivity, conversion efficiency and stability of catalyst will be clarified in the process of gas-liquid-solid multiphase reaction. The numerical model will be put forward to establish the synergistic regulation of mass transfer and reaction, and the type of reactant and concentration field in the channel of monolith catalyst will be simulated. The optional process regulation will be implemented in process of gas
