CO₂ Capture Using Solutions of Alkanolamines and Aminosilicones

Abstract

Tertiary amino alcohols have been shown to be effective co-solvents for CO 2 capture when used in conjunction with aminosilicones. In some cases, they demonstrated a marked increase in CO 2 capture compared to an equivalent weight loading of triethylene glycol and also showed a lower viscosity at a given CO 2 loading. These materials may be useful as co-solvents in carbon capture processes using aminosilicones.
