Abstract:

Carbon capture is one of the most critical technical means to reduce CO2 emissions. Compared with various carbon capture technologies, membrane separation features operational simplicity, low energy consumption and low ecological footprint, which has attracted wide attention. The complete research chain of membrane technology for CO2 separation includes the development of membrane materials, the large-scale preparation of membranes, the structural design of membrane modules, and the integrated simulation and optimization of membrane separation processes and devices. Focusing on the above four links to develop the CO2 separation membrane technology, this article reviews the technical and research progress worldwide and analyzes the bottleneck problems of the CO2 separation membranes from laboratory research to industrial scale-up. The research results accumulate by the team led by Tianjin University in each technical link are also summarized. Based on the above description, the possible research direction to further develop membrane technology for carbon capture is proposed.

Key words: CO2 separation membrane, carbon capture, membrane module, membrane process, industrialization
