The present disclosure provides novel solid sorbents synthesized by the reaction of polyamines with polyaldehyde phosphorous dendrimer (P-dendrimer) compounds. The sorbents are highly stable and exhibit rapid reaction kinetics with carbon dioxide, making the sorbents applicable for carbon capture, and can be easily regenerated for further use. The material is stable to aqueous and organic media, as well as strong acid and bases. The sorbent maintains full capacity over extended use. The material can be used for CO2 capture from pure CO2 streams, mixed gas streams, simulated flue gas, and ambient air. Additionally, the material can be adhered to surfaces for reversible CO2 capture applications outside of bulk particle-based processes.
本公开提供了由多胺与多醛磷树枝状聚合物(P-树枝状聚合物)化合物反应合成的新型固体吸附剂。这种吸附剂稳定性高,与二氧化碳的反应动力学速度快,因此适用于碳捕集,并且易于再生以继续使用。这种材料对水性和有机介质以及强酸和强碱都很稳定。吸附剂在长时间使用后仍能保持饱满的容量。这种材料可用于纯二氧化碳流、混合气体流、模拟烟道气和环境空气中的二氧化碳捕集。此外,该材料还可粘附在表面上,用于基于大颗粒工艺之外的可逆二氧化碳捕集应用。
