Enhanced capacity to CO_2 sorption in humid conditions with a K-doped biocarbon
|
摘要
Solid sorbents with enhanced capacity and selectivity towards CO_2 are crucial in the design of an efficient capture process.Among the possible alternatives,K_2CO_3-doped activated carbons have shown high CO_2 capture capacity and rapid carbonation reaction rate.In this work,a sustainable and low-cost approach is developed with a biomass-based activated carbon or biocarbon as support.The CO_2 capture performance in cyclic sorption–desorption operation and the sorption kinetics have been investigated under different scenarios in a purpose-built fixed-bed set-up.Independent of the H_2O concentration in the flue gas,a constant relative humidity(～20%)in the K_2CO_3-doped biocarbon bed promoted the carbonation reaction and boosted the CO_2 sorption capacity(1.92 mmol/g at 50℃ and 14 kPa partial pressure of CO_2).Carbonation is slower than physical adsorption of CO_2 but wise process design could tune the operation conditions and balance capture capacity and sorption kinetics.
