Adsorption separation of ethylene and ethane:mechanisms,materials and industrial prospects
系统综述了乙烯/乙烷吸附分离技术的最新研究进展,重点介绍了分子筛、金属有机骨架(MOFs)2类主流吸附材料。围绕从分子结构设计出发到分子筛分、π络合、门控效应分离机制,剖析了2类材料在材料创制、结构调控及核心瓶颈应用实践等方面的研究现状,总结了乙烯或乙烷优先吸附材料的设计策略与性能特征。研究认为,吸附剂综合性能协同优化、竞争吸附位点精准调控、乙烷优先吸附剂低成本开发等是未来研究方向。
The recent advances in ethylene/ethane adsorption separation technology was systematically reviewed,focusing on two mainstream adsorbent materials:molecular sieves and metal-organic frameworks (MOFs).Covering topics ranging from molecular structural design to separation mechanisms such as molecular sieving,π-complexation and gating effects,the paper analyzes the current state of research on these two material classes in terms of material synthesis,structural regulation,and key challenges in practical applications.It also summarizes design strategies and performance characteristics of materials exhibiting preferential adsorption of either ethylene or ethane.The study identifies future research directions toward efficient ethylene/ethane adsorption and separation,including the synergistic optimization of adsorbent performance,precise regulation of competitive adsorption sites,and the low-cost development of ethane-selective adsorbents.
