用于燃烧后CO2捕集系统的胺基固态吸附材料研究进展

随着工业化的发展和大量化石燃料的消耗，大量的CO₂气体排放到大气中并引发了一系列严重的环境问题，而采用燃烧后CO₂捕集技术可以有效地应对这一问题。寻找一种高效吸附、稳定、价格低廉的固态吸附材料对于开展燃烧后CO₂捕集系统的研究具有重要的实际意义。近年来，胺基固态吸附材料因其高CO₂吸附能力和高吸附选择性成为研究的热点。本文综述了近年来国内外学者对不同胺基固态吸附材料在合成方法、载体材料选择以及性能测试等方面进行的研究，重点讨论了以沸石分子筛、介孔硅分子筛、多孔碳和金属有机骨架为载体的胺基固态吸附材料对CO₂的吸附行为，并指出多孔载体材料的结构改进及有机胺和促进剂的合理选择将会成为未来胺基固态吸附材料的重点研究方向。

Recent advances in amine-based solid sorbents for post-combustion CO2 capture

The anthropogenic CO₂ emission by combustion of fossil fuels is mainly responsible for the global warming. Post-combustion CO₂ capture is one promising approach to reduce the CO₂ emission from power plants. It is very important to find solid sorbents that are highly efficient, stable and cost-effective for post-combustion CO₂ capture. Recently, many researchers have paid attentions to the development of novel amine-based solid sorbents because of their high CO₂ adsorption capacity and selectivity and easy regeneration. Amine-based solid sorbents can be prepared by the incorporation of diverse organic amines into the pore structures of the support materials by physical impregnation, grafting or direct-synthesis. This paper reviews novel amine-based solid sorbents prepared with different supporting materials including zeolite, mesoporous silica, porous carbon materials, and metal organic frameworks(MOFs) in recent years. Finally, it is also proposed that the development of novel supporting materials with hierarchically porous structure and the selection of amines and accelerants will be hot spots in future studies.
