イオン液体静電噴霧の特性解析と高効率CO₂分離回収への応用

抄録

Ionic liquids exhibit outstanding ability of carbon dioxide (CO₂) absorption. Aiming at further CO₂ higher absorption rate, we attempted to develop ionic liquid electrospray CO₂ capture system in this study. Since electrospray generates ultrafine droplets, surface absorption reaction at the interface can be enhanced remarkably. Droplets of 200~1000 nm were successively generated by the electrospray, and the CO₂ absorption amount integrated for 20 minutes increases by 220% by electrospray.
