Zusammenfassung:	A novel blend of piperazine (PZ) and a second amine compound is provided as a superior solvent for CO2 capture from coal-fired flue gas. Blending PZ with various second amine compounds can remediate the precipitation issue of concentrated PZ while maintaining its high CO2 absorption capacity and rate, and high resistance to oxidative degradation.
