摘　　要：沸石杂化炭膜具有气体渗透分离性能可调性强、热稳定性和化学稳定性好等优点,有望解决制约传统炭膜的渗透性与选择性间互相制约的关系。但因沸石在杂化炭膜制备过程中所受的影响因素多,使得人们对沸石作用规律和作用机理缺乏清晰的了解。本文回顾了全球沸石杂化炭膜制备技术中的沸石种类、粒径、用量、掺杂方式、炭化条件等方面对气体分离性能的影响,并分析了沸石作用原理和应用前景。提出为了实现可控性制备,不仅要通过深入实验研究掌握沸石作用规律,也要通过建立模型着重进行理论研究。Zeolite hybrid carbon membranes take the advantages of superior thermal and chemicalstability, and excellent controllability of gas separation properties. They are expected to resolvethe contradictory trade-off relationship between the gas permeability and selectivity for traditionalcarbon membranes. However, it lacks of the clear understanding on the function rules andmechanisms of zeolites due to the numerous factors in the preparation of zeolite hybrid carbonmembranes. This paper reviews the effects of fabrication factors, including zeolite types,particulates, usage, hybridization methods, carbonization condition, etc, on the gas separationperformance of hybrid carbon membranes reported globally. In addition, the function theories ofzeolite and the application prospects of hybrid carbon membranes are also analyzed. It is proposed thatit would carry out the experimental work to deeply master the function rules of zeolite and thetheoretical study based on model establishment in the viewpoint of controllable fabrication.
