Ethylene (C2H4) serves as a core raw material in the modern chemical industry, where its efficient separation and purification are of paramount importance. Compared to traditional distillation technology, adsorption separation technology offers significant advantages, including reduced energy consumption, lower costs, and simpler operational procedures. Ethane (C2H6)-selective adsorbents can directly obtain high-purity C2H4 through a single-step adsorption, simplifying the separation process and reducing energy consumption. Developing efficient C2H4 separation and purification technologies is a major demand for energy conservation, consumption reduction and green development in the chemical industry. The key to this research lies in the design and preparation of high-performance C2H6-selective adsorbents. The advent of Metal-organic framework (MOF), characterized by their high designability and adjustability, has significantly advanced the research and development of C2H6-selective adsorbents. By strategically designing active sites and precisely controlling pore environments, a diverse range of C2H6-selective adsorbents have been continuously developed. However, when facing actual separation systems and complex industrial application scenarios, the performance of these materials still needs to be improved, and there is an urgent need for further systematic research on the structure-activity relationship of the C2H6 adsorption mechanism. This study provides a comprehensive review of the research progress in C2H6-selective adsorbents over the past 15 years, delving into their structural design methodologies, such as flexible gate-opening effects, metal site modifications, and surface potential regulation. It also elaborates in detail on the influence mechanisms of different methods on the adsorption selectivity and capacity. In addition, it emphasizes the key challenges that C2H6-adsorbents must overcome in the face of industrial applications, including cyclic stability, green large-scale synthesis, and the establishment of new separation processes. It is expected to lay a theoretical foundation for the precise construction and separation application of high-performance C2H6-adsorbents, and to promote the technological innovation and transformative development of the olefin separation industry.
