MOFs用于炔烃/烯烃高效分离的近期研究进展

Recent research progress of MOFs for efficient separation of alkynes/alkenes

传统的低碳烃气体分离技术能耗高,容易造成一定的环境压力,如低温蒸馏和溶剂萃取.此外,由于工业和技术的发展以及对产品更高的要求(如纯度),传统的分离方法已无法满足需求.金属有机框架(MOFs)作为一类相对新颖的多孔有机-无机杂化材料,因其可控的拓扑结构和多样的化学微环境,在低碳烃分离和纯化领域受到广泛关注.文章概述了MOFs作为分离和纯化低碳烃气体吸附剂具有的特性,重点关注了MOFs材料在炔烃/烯烃气体分离领域的应用进展.

Traditional separation technologies of low-carbon hydrocarbon gases such as cryogenic distillation and solvent extraction have high energy consumption and are easy to cause certain environmental pressure. In addition, due to the development of industry and technology and the higher requirements for products(such as purity), traditional separation methods can no longer meet the demand. As a relatively novel class of porous organic-inorganic hybrid materials, metal-organic frameworks(MOFs) have received extensive attention in the field of low-carbon hydrocarbon separation and purification due to their controllable topological structure and diverse chemical microenvironment. In this paper, the characteristics of MOFs as adsorbents for the separation and purification of low carbon hydrocarbon gases are summarized, and the application progress of MOFs materials in the separation of alkynes/alkenes is emphasized.
