摘　　要：二氧化碳捕集与封存技术(CCS)是针对大气CO2含量增高导致的全球气候变暖而提出的全球性解决方案。有机胺吸收法作为经济与技术层面最成熟的技术,是实现二氧化碳捕集的重要工艺过程。设计并合成了一种水溶性低聚胺作为CO2吸收剂,并对其结构进行了表征。同时利用核磁共振碳谱对其吸收与解吸收CO2的能力进行了测试。测试结果表明:制备的水溶性低聚胺对CO2有吸收-解吸收能力。Carbon Dioxide Capture and Storage Technology(CCS)has been considered as the globalism solution scheme of global warming caused by being elevated atmospheric CO2 levels.As the most mature technology at the economic and technical level,the organic amine absorption method was an important process for achieving carbon dioxide capture.In this paper,a water-soluble oligoamine was designed and synthesized as a CO2 absorbent,and its structure was char-acterized.At the same time,the ability of absorbing and desorbing CO2 was tested by nuclear magnetic resonance spec-troscopy.The test results show that the prepared water-soluble oligoamine has absorption-desorption capacity for CO2.
