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.
本工作首次报道了使用氨基硅油溶剂混合物来捕获 CO(2)。为了保持液态，采用了羟乙醚共溶剂，从而使 CO(2)在溶剂混合物中得到增强的物理吸附。在 6 个循环中证明了捕获溶剂体系的再生能力，吸收等温线表明在 30%MEA 以上时动态 CO(2)容量增加了 25-50%。此外，还验证了连续 CO(2)吸收的概念验证。此外，用于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。
