这项工作描述了第一份报告的使用氨基硅油溶剂混合物的捕获CO（2）。为了保持液体状态，使用羟基醚共溶剂，其允许溶剂混合物中的CO（2）的增强的物理吸附。在6个循环中证明了捕获溶剂系统的再生，并且吸收等温线表明动态CO（2）容量比30%MEA增加25- 50%。此外，验证了连续CO（2）吸收的概念验证。此外，预测氨基硅油溶剂与CO（2）的反应热的模型与实验结果吻合良好。
This work describes the first report of the use of an aminosilicone solvent mix for the capture of CO(2). To maintain a liquid state, a hydroxyether co-solvent was employed which allowed enhanced physisorption of CO(2) in the solvent mixture. Regeneration of the capture solvent system was demonstrated over 6 cycles and absorption isotherms indicate a 25-50 % increase in dynamic CO(2) capacity over 30 % MEA. In addition, proof of concept for continuous CO(2) absorption was verified. Additionally, modeling to predict heats of reaction of aminosilicone solvents with CO(2) was in good agreement with experimental results.
