摘要

在聚合级乙烯生产中，深度脱除微量乙炔是保障下游工艺安全与催化剂稳定性的关键环节。相较于能耗高且脱除性能有限的传统技术，吸附分离法因具有绿色节能潜力而备受关注，其核心在于开发可精准辨识乙炔的高分离性能吸附剂。由于乙炔与乙烯在分子尺寸等物理性质上高度接近，开发精准辨识乙炔分子的吸附剂极具挑战。金属有机框架（MOFs）材料凭借可调控的孔道结构与表面化学性质，在此领域展现出巨大应用潜力。系统综述了用于乙炔/乙烯吸附分离的MOFs材料研究进展，重点归纳了氢键识别与柔性响应等核心设计思路及配体功能化、孔径/形状调控与孔空间分割等构筑策略对分离性能的提升作用，并总结了绿色放大合成与颗粒成型的关键技术进展。未来研究需由“本征选择性”迈向“工程可用性”，聚焦复杂工况稳定性、传质动力学、成型强化、工艺集成与经济性评估，加速高性能MOFs材料的工业化应用进程。

Abstract

In polymer-grade ethylene production

the deep removal of trace acetylene is an essential step in ensuring downstream process safety and catalyst stability. Compared to traditional technologies with high energy consumption and limited removal performance

adsorption separation method has attracted much attention due to its green and energy-saving potential. Its core lies in the development of high-performance adsorbents that can accurately identify acetylene. Due to the close physical properties such as molecular sizes between acetylene and ethylene

developing adsorbents that accurately identify acetylene molecules is extremely challenging. Metal-organic frameworks (MOFs) materials have shown great application potential in this field due to their controllable pore structures and surface chemical properties. Research progress on MOFs materials for adsorption separation of acetylene/ethylene was systematically reviewed. The core design ideas of hydrogen bond recognition and flexible response

as well as the construction strategies of ligand functionalization

pore size/shape control and pore space segmentation

were summarized to enhance separation performance. The key technological progress on green amplification synthesis and particle shaping was also summarized. Looking forward

the research needs to move from “intrinsic selectivity” to “engineering applicability”

focusing on the stability of complex working conditions

mass transfer kinetics

forming enhancement

process integration and economic evaluation

accelerating the industrial application process of high-performance MOFs materials.
