CO2 Capture Using Solutions of Alkanolamines and Aminosilicones

Tertiary amino alcohols have been shown to be effective co-solvents for CO2 capture when used in conjunction with aminosilicones. In some cases, they demonstrated a marked increase in CO2 capture compared to an equivalent weight loading of triethylene glycol and also showed a lower viscosity at a given CO2 loading. These materials may be useful as co-solvents in carbon capture processes using aminosilicones.
