Effects of water vapour on CO2 capture with vacuum swing adsorption using activated carbon

Green coffee based CO2 adsorbent with high performance in postcombustion conditions

“…Experimental and simulation studies have confirmed these results using different cycle configurations [5,28,29]. The use of activated carbons could even avoid the need of a drying step by simultaneous removal of CO 2 and H 2 O from flue gas [30,31].…”

Water vapour adsorption by a coffee-based microporous carbon: effect on CO2capture

“…The interaction of water molecules with the hydrophobic carbon surface is less favoured, especially at low relative pressures. This facilitates the regeneration of the carbon adsorbents working in humid conditions by vacuum swing adsorption (VSA) or temperature aided vacuum swing adsorption (VTSA), eliminating the need for a dehydration unit with the subsequent operating and installation cost savings.…”

“…To date, the majority of the published literature on CO 2 capture by adsorption deals with dry gas mixtures. The influence of H 2 O on the CO 2 capture performance has only gained interest recently . In this work the effect of the coadsorption of water vapour over the adsorption of CO 2 on PPC has been evaluated under dynamic conditions using a fixed‐bed adsorption unit and synthetic flue gas mixtures in the presence and absence of water vapour.…”

Separation of CO2 in a Solid Waste Management Incineration Facility Using Activated Carbon Derived from Pine Sawdust

“…Although the adsorption equilibrium and mechanisms of water vapor adsorption on activated carbon have been widely investigated [16][17][18][19], very few studies have used fixed-bed experiments to gain insight into the adsorption dynamics of water vapor on activated carbon [20][21][22].The impact of water vapor on the capacity of biomass-based activated carbons to capture CO 2 has been evaluated: adsorption equilibrium data, measured for CO 2 , N 2 , O 2 and H 2 O, and breakthrough experiments performed under different relative humidity were conducted to explore the mutual influence of CO 2 and H 2 O adsorption.…”
