  • Chemisorption Working Capacity And Kinetics Of CO2

    The adsorption of CO 2 shows very fast reaction kinetics followed by a slower adsorption.. It is very important to compare the pretreatment or the desorption step (history of the material). • KMG30 has a adsorption mechanism for H 2 O completely different compared to CO 2.. Both, CO 2 and H 2 O working capacity are strongly increased by increasing the partial pressure.
