The study of CO2 absorption intensification using porous media material in aqueous AMP solution
In this work, the performance of CO2 absorption into aqueous 2-amino-2-methyl-propanol (AMP) solution was investigated by measuring the amount of CO2 in the liquid phase during CO2 absorption process to identify initial CO2 absorption rate. Then, the porous media material named as MCM41 was introduc...
