Flash carbonization is an attractive yet simple route for the preparation of biomass (sawdust) derived carbons that exhibit attractive CO2 uptake of up to 5.0 mmol g−1 (at 25 °C and 1 bar), and exceptional working capacity for pressure or vacuum swing adsorption processes under simulated flue gas conditions.

Adsorption Of Co2

Metal-organic framework-808 has been functionalized with 11 amino acids (AA) to produce a series of MOF-808-AA structures. The adsorption of CO2 under flue gas conditions revealed that glycine- and DL-lysine-functionalized MOF-808 (MOF-808-Gly and -DL-Lys) have the highest uptake capacities. Enhanced CO2 capture performance in the presence of water was observed and studied using single-component sorption isotherms, CO2/H2O binary isotherm, and dynamic breakthrough measurements. The key to the favorable performance was uncovered by deciphering the mechanism of CO2 capture in the pores and attributed to the formation of bicarbonate as evidenced by 13C and 15N solid-state nuclear magnetic resonance spectroscopy studies. Based on these results, we examined the performance of MOF-808-Gly in simulated coal flue gas conditions and found that it is possible to capture and release CO2 by vacuum swing adsorption. MOF-808-Gly was cycled at least 80 times with full retention of performance. This study significantly advances our understanding of CO2 chemistry in MOFs by revealing how strongly bound amine moieties to the MOF backbone create the chemistry and environment within the pores, leading to the binding and release of CO2 under mild conditions without application of heat.

Water Front

The working capacity of 13X zeolite was considerably reduced when feeding a vacuum swing adsorption (VSA) carbon capture process with a high (~10%) water humidity level gas stream. To effectively tackle the water issues in real flue gas and keep the capital costs at a economical level without adding any pre-drying equipment, multiple-layer VSA technology was investigated in this study. Three configurations of multi-layer experiments were designed and conducted: double layers with 13X and Sorbead, triple layers with LiX zeolite +13X+Sorbead and triple layers with 13X+Sorbead+ACF. Experimental results showed that the water front was successfully contained within the pre-layers at cyclic steady states. More importantly, our one-bed systematic cyclic experiments could concentrate CO2 from 12% to 61% with a CO2 recovery of 77% under the double-layer configuration. Meanwhile, as a comparison, the LiX triple-layer experiment yielded a good CO2 recovery of 81% and productivity of 0.0132 mol/(kg•h) under the same operational condition as double layers. The ACF triple-layer experiments illustrated that the water front was retained better than the double layer case due to the larger water adsorption capacity of ACF though a higher pressure drop was observed as result of tight packing.
