中文摘要： 膜催化反应是近年来发展起来的具有广泛应用前景的新型催化反应技术，可以同时完成催化反应和产品分离两个过程,从而实现催化-反应-分离一体化,具有简化流程，节省投资，降低能耗等优点。本项目通过对催化转化合成气制备二甲醚的分子筛膜催化反应器进行微观结构的设计和调控,借助APTES（3-氨丙基三乙氧基硅烷）和多孔基体及分子筛膜之间的共价键合作用，在多孔基体表面制备出具有三明治复合结构的反应分离一体化双功能分子筛膜反应器并用于高效催化转化合成气制备二甲醚。详细考察基体微观结构及表面性能和合成工艺参数对反应分离一体化双功能分子筛膜的微观结构和分离性能的影响，探讨双功能分子筛膜表面的微观结构、催化活性组分晶粒尺度等微观效应与二甲醚生产效率的相关性，进而从理论和实验上深入认识反应与分离耦合过程中催化材料和分子筛膜材料之间以及催化反应过程和膜分离过程之间的相互作用，为进一步建立无机膜催化理论提供坚实基础。

英文摘要： Membrane catalysis reaction which was developed recently is a promising and novel catalytic reaction technology with wide application, and it can synchronously fulfill two processes of catalysis reaction and production separation,thus achieving the integrative processes of catalysis-reaction-separation. Membrane catalysis reaction has many advanteges, such as process simplify, cost save and engergy reduce. This project focuses on the design and control of the microstructure of the zeolite membrane reactor for the catalytic reforming syngas to produce dimethyl ether. Through the reaction of the covalent bonding between APTES (3-aminopropyltriethoxysilane)and porous supports as well as zeolite membranes, a novel reaction-separation integrative and bi-functional zeolite catalytic membranes reactor with sandwiche structure is prepared on porous support to use for the production of dimethyl ether based on the the catalyst reforming syngas.The effects of the microstructure and surface properties of the supports as well as the synthesis factors on the microstructure and separation performances of the reaction-separation integrative and bi-functional zeolite membranes are investigated.The relations between the microstructure ofthe zeolite membranes and the microeffect like crystals size of the catalysis active component
