Abstract

En 中文

• Ternary blend amines (AMP-AEP-MDEA and AMP-HMDA-MDEA) were developed for CO2 capture. • Both systems showed superior CO2 absorption-desorption compared to 30 wt% MEA. • AMP-AEP-MDEA exhibited excellent thermal stability with 25.1% degradation at 150 °C. • Rigid AEP makes AMP-AEP-MDEA more thermally stable than flexible HMDA blends.
