多孔液体在CO_(2)捕集与利用领域的研究进展

Research progress on porous liquids for CO_(2)capture and utilization

为助力中国早日实现“双碳”目标,深入落实化工领域绿色低碳可持续发展的重要举措,吸附/吸收耦合有望成为气体分离的绿色变革性分离技术,其关键是高性能吸附(收)材料的开发。多孔液体作为一类具有永久孔隙的液体材料,兼具了液体吸收剂的易于管道输送、传质传热效果好等优点和固体吸附剂的高比表面积、高孔隙率等优点,有望成为新一代CO_(2)捕集的绿色变革性介质。该文首先简单介绍了多孔液体发展历程;然后,重点对多孔液体在CO_(2)的吸附/吸收、膜分离、催化转化等领域的应用进行了论述,并对多孔液体性能和优缺点进行了分析归纳。最后,对多孔液体目前面临的挑战和未来发展趋势进行了展望。

In order to achieve the national"dual carbon goal"as soon as possible and implement the important measures of green,low-carbon and sustainable development in the chemical industry,adsorption/absorption coupling is expected to become a green and revolutionary separation technology for gas separation,and the key is to develop high-performance adsorption materials.Porous liquids,a kind of liquid material with permanent pores,combine the advantages of liquid absorbents(such as easy pipeline transportation,efficient mass and heat transfer)with those of solid adsorbents(such as high specific surface area and porosity),and are expected to be a new generation of green,transformative media for CO_(2)capture.In this review,the development of porous liquids was briefly introduced.The applications of porous liquids in CO_(2)adsorption/absorption,membrane separation,and catalytic conversion were then discussed in detail,followed by summarization on the performances,advantages and disadvantages of porous liquids.Finally,the current challenges and future development trends of porous liquids were prospected.
