摘要
Solid phase adsorption is expected to significantly reduce the cost of CO2 capture, and thereby promote the wide deployment of carbon capture, utilization and storage, which is of vital importance for high quality achievement of carbon neutrality. High performance adsorbent is the current research hotspot in this field, which has received extensive attention from both academia and industrial aspects. This paper focused on zeolite-based CO2 adsorbents. Following the research and development trend of the materials, the recent progresses were reviewed from the aspects of pure silicon aluminum molecular sieve, ion exchange modification, amination function modification, hydrophobic modification and new adsorption mechanism of “Trapdoor”. The design strategy, synthesis method, mechanism of enhancing CO2 adsorption and related contents were summarized, and their pros and cons were compared. Based on this, the influence of temperature, pressure and composition of flue gas was discussed in the context of potential scenarios of CO2 capture. Moreover, by taking considerations on possible issues of large-scale application, suggestions for further work were proposed. © 2023 Chemical Industry Press. All rights reserved.
