摘要/Abstract

摘要：

二甲苯异构体的分离与纯化是石油化学工业的重要过程之一，但二甲苯异构体的结构和性质极其接近，常规精馏和深冷结晶法分离能耗高、生产效率低。模拟移动床色谱是主流的二甲苯异构体分离技术，但作为吸附剂的分子筛在吸附容量和分离选择性两方面均存在不足。金属有机框架和超分子材料具有组装自由、结构多样和性质可调等优点，可通过构建极性孔环境或精准设计孔道尺寸与形状实现二甲苯异构体的高效辨识与分离。本文综述了金属有机框架和超分子材料在二甲苯异构体吸附分离中的研究进展，从静电作用、尺寸筛分和形状筛分等方面探讨了二甲苯异构体分离的内在机制，总结了金属有机框架在二甲苯分离领域存在的问题和局限，并对未来发展方向进行了展望。

Abstract:

The separation and purification of xylene isomers is one of the important processes in the petrochemical industry. However, the structures and properties of xylene isomers are extremely close. Conventional distillation and cryogenic crystallization separation methods have high energy consumption and low production efficiency. Simulated moving bed chromatography is the primary technology for separating xylene isomers, but zeolites as the adsorbents are insufficient in terms of adsorption capacity and separation selectivity. Metal-organic frameworks and supramolecular materials possess advantages such as flexible assembly, structural diversity, and adjustable properties. They can achieve highly efficient discrimination and separation of xylene isomers through the construction of polar pore environment and fine-turning of the size and shape of pore channels. This review summarizes the research progress of metal-organic frameworks and supramolecular materials in the adsorption and separation of xylene isomers, discusses the intrinsic mechanisms of xylene isomers' separation from aspects including electrostatic interactions, size sieving, and shape sieving. It also summarizes the problems and limitations of metal-organic frameworks in the field of xylenes separation and provides a prospective on future development directions.

Key words: adsorption, separation, adsorbents, xylene isomers, para-xylene, metal-organic frameworks
