Abstract
|
|
|
The adsorption characteristics of CO2 gas on impregnated activated carbons with MEA (Mono-ethanolamine) and AMP
(2-Amino 2-methyl 1-propanol) were studied to improve the adsorption ability of CO2 gas on activated carbon. The
equilibrium adsorption capacity of CO2 gas was increased by increment of impregnation concentration up to 40 %, but
decreased above 50 %. The adsorption capacity of activated carbon impregnated with AMP was higher than activated carbon impregnated with MEA. The breakthrough was fast according to increment of inlet concentration of CO2 gas.
