Post-combustion carbon dioxide capture technology and progress of application

Carbon dioxide,as one of the main greenhouse gases, has caused an impact on the whole globe climate and environment due to its massive emission. Therefore, it is urgent to develop economical and effective carbon capture technology. At present, carbon capture technology mainly includes absorption separation, adsorption separation, membrane separation and cryogenic separation. Firstly, the development status, application research progress and future development trends of the carbon capture technology were reviewed. Moreover, the main post-combustion carbon capture projects at home and abroad were also summarized. The advantages and disadvantages of each carbon capture technology were compared, and the difficulties and challenges faced by the capture technology were emphasized. In conclusion, the current main carbon capture technologies are difficult to independently achieve efficient, energy-saving, economical carbon capture separation, which need to choose the suitable separation technology for different application scenarios according to the given application suggestions. Lastly, the research studies of mixed capture technology were briefly introduced, indicating that the combination of capture technologies may be a feasible method to break the bottleneck of single capture technology.
