Study on carbon dioxide absorption kinetics in aqueaus solutions of potassium carbonates activated with alkanolamines in a pressure bubble reactor with stirrer
Four amine activators were used for acceleration of the CO2 absorption in aq. K2CO3 solns. in a lab. bubble reactor at 30-80 degrees C under 4 bar to det. the absorption kinetics. A dimentionless enhancement factor was calcd. NH2(CH2CH2NH)(4)H and MeNHCH2CH2OH were the best activator of absorption.
