Abstract

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.
