FTO过程作为强放热复杂串行反应过程，新型高效催化剂的研制应协同“传质/传热”与优化流体流动及传递性能的研究。微结构化催化剂/反应器（MCRs）技术已被广泛证实能显著优化固体催化剂床层的流体力学行为和提高床层内部的传质/传热性能。本课题基于“自上而下（Top-Down）”的反应器（Top，流动与传递）-催化剂（Down，表界面反应）一体化设计理念创制新型微结构化Fe基整装式催化剂，以实现反应器内流动和传递与表界面FTO催化反应的协同耦合，创制一种选择性高、导热性好、稳定可再生和渗透性能好的整装式结构化催化剂。研究该催化剂诸如几何构型、氧化物（分子筛）厚度、分子筛硅铝比与晶面取向、以及催化活性组分配比与分布等宏微纳结构与物化性质对低碳烯烃选择性的调控关系。建立模拟、动力学和反应产物及床层温度分布测定实验方法，研究结构催化剂的几何构型、水力学和传递性质，及其与表界面催化反应的传递耦合作用机制。

Fischer-Tropsch to olefins (FTO) is a strong-exothermic and complex serial reaction, and there should be an exigent investigation on the process intensification of mass/heat transfer coupling with fluid-flow and transferring ability. Development and use of the microstructured catalyst is a promising strategy to improve hydrodynamics in combination with enhanced heat/mass transfer, thus being a major field in heterogeneous catalysis. Herein, the principle goal is to raise and then maintain a high selectivity to lower olefins of the FTO process, and therefore we propose a 'Top-Down' design FTO strategy for achieving this goal. Via the synergistic coupling of the mass/heat transfer inside reactor with the surface catalysis, this strategy can provide an efficient and effective monolithic catalyst with the combination of large void volume (continuously adjustable), high heat/mass transfer, narrow resistance time distribution, micro- to macro-engineered hierarchical pore structure, core-shell structure, and good rigidity/robustness. Effects of features of the “fiber@oxide(zeolite)-FeMnK” core-shell catalysts in terms of geometry, textural properties, catalytic species distribution, etc., will be systematically investigated on their FTO selectivity and stability. Computational fluid dynamics (CFD) code FLUENT in combination with experimental testing will be employed to simulate the temperature and reaction distributions inside such microfibrous-structured catalytic bed, demonstrating the process intensification benefitted from the enhanced heat/mass transfer and improved hydrodynamics.
