非胺类CO2吸收剂的研究进展

针对CO₂所带来的全球气候变化问题，本文综述了可用于捕集CO₂的非胺类吸收剂类型，认为氨基酸盐、氨基酸-碳酸钾体系、离子液体、生物型吸收剂、钙基吸收剂分别具有较高的CO₂循环吸收负荷、低毒性、热稳定性好、较优的生物相容性、钙源易获取的优势，可以弥补胺类吸收剂在吸收-解吸CO₂时腐蚀性强、再生能耗高、对环境产生二次污染等方面的不足。氨基酸盐、氨基酸-碳酸钾体系可应用于具有一定规模的CO₂捕集工业中；离子液体可应用于精准、绿色环保去除CO₂工业中；生物型吸收剂可用于规模小、CO₂浓度低的工业中；钙基吸收剂可运用于CO₂浓度高的工业中。上述吸收剂皆具有一定的工业前景。

Research progress in non amine carbon dioxide absorbents

In response to the global climate change issues brought about by carbon dioxide, this article reviews the types of non amine absorbents that can be used to capture carbon dioxide. It is believed that amino acid salts, amino acid potassium carbonate systems, ionic liquids, and biological absorbers have the advantages of high carbon dioxide cycle absorption load, low toxicity, no degradation, good thermal stability, and low cost, respectively, which can compensate for the strong corrosiveness of amine absorbers in absorbing and desorbing carbon dioxide Shortcomings in terms of high energy consumption and secondary pollution to the environment due to regeneration. Amino acid salts and amino acid potassium carbonate systems can be applied to carbon dioxide capture industries with a certain scale; Ionic liquids can be applied in precise, green, and environmentally friendly carbon dioxide removal industries; Biological absorbents can be used in small-scale and low carbon dioxide concentration industries. The above absorbents all have certain industrial prospects.
