Abstract:

The separation and purification of low molecular weight hydrocarbon (C1—C3) mixtures is a critical and energy-consuming industrial process. Therefore, it is imminent to develop solid adsorption materials that can selectively adsorb and separate C1—C3 molecules with low energy consumption under mild conditions. As a relatively novel class of porous organic-inorganic hybrid materials, metal-organic frameworks (MOFs) have received extensive concerned in the field of low-carbon hydrocarbon separation and purification due to its precisely controllable pore structure and diverse chemical microenvironment. This work outlined the characteristics of MOFs as adsorbents for the separation and purification of low-carbon hydrocarbon gases. The focus was on the application progress of MOF materials in the separation of C1 (CO2/CH4), C2 and C3. The three common separation mechanisms of MOFs materials in the separation of C1—C3 hydrocarbons were summarized firstly, and then the adsorption and separation performance of MOFs materials for common C1—C3 hydrocarbon molecules in recent years were reviewed accordingly. The structure-activity relationship of MOFs in the separation of C1—C3 hydrocarbons was analyzed. The control concepts and methods of the pore size/shape, skeleton flexibility and surface function of MOFs materials were summarized. The high cost of MOFs materials, poor hydrothermal stability, and the difficulty of precise detection of the relationship between the host and the object were proposed, which restricted their application and development. Future research should be focused on developing low-cost, diversified and specific new ligands, constructing composite adsorbents, and clarifying the host and guest properties of the separation system during the adsorption and separation process. It would provide an exploration direction for the directional design of MOFs materials for the low-carbon hydrocarbons separation.

Key words: metal-organic-frameworks (MOFs), adsorbents, separation, low-carbon hydrocarbons

摘要:

低碳烃(C1~C3)混合物的分离和纯化是化工过程中最重要且耗能最大的过程单元之一,开发温和条件下低能耗高选择性吸附分离C1~C3分子的固体吸附材料迫在眉睫。金属有机框架材料(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。本文概述了MOFs作为分离和纯化低碳烃气体吸附剂的特性,重点关注了MOFs材料在C1(CO2/CH4)、C2、C3烯/烷烃以及烯/炔烃分离领域的应用进展。首先归纳了MOFs材料在C1~C3烃类物质分离过程中的三种常见分离机制,并据此回顾了近年来MOFs材料对常见C1~C3烃类分子的吸附及分离性能;分析了MOFs材料在C1~C3烃类物质分离过程中的构效关系,总结了MOFs材料的孔道尺寸/形状、骨架柔性和表面功能的调控理念与方法,并提出MOFs材料成本高、水热稳定性差、主客体关系难以精准探测等制约其应用发展的现状。文章指出未来研究重点为开发低成本多样化专一性的新型配体,构造复合型吸附剂,并明确吸附分离过程中分离体系主客体性质,为MOFs材料用于低碳烃分离的定向设计提供了探索方向。
