N2 - In this work, 13C NMR spectroscopy was used to study the reaction process of the 2M blended amine of MEA-DEA(1:1) with CO2. All the concentrations of speciations in the solutions in the CO2 loading range of 0-0.7 mol CO2/mol amine at the temperature of 301K were calculated in order to better understand the reaction process of blended amine reaction with CO2. The results show that M E A is more competitive than DEA at lower CO2 loading. And at higher CO2 loading, both MEA and DEA react with CO2.
