The high energy consumption of CO2-loaded solvent regeneration is the biggest impediment for real application amine-based CO2 capture process. To lower requirement, three Fe promoted SO42–/ZrO2 supported on MCM-41 (SZMF) catalysts with different iron oxide content (5%, 10%, and 15%) were synthesized applied rich monoethanolamine solution process at 98 °C. Results reveal that use SZMF hugely enhanced desorption performances (i.e., factor) by 260–388% reduced heat duty about 28–40%, which...
A strategy for decreasing the viscosity variation in process of CO2 capture by amino-functionalized ionic liquids (ILs) through formation intramolecular hydrogen bond was reported. Different with dramatic increase during uptake traditional ILs, slight or even decrease achieved introducing a N O atom as acceptor into anion, which could stabilize active produced carbamic acid. Quantum chemical calculations and spectroscopic investigations demonstrated that between introduced acid key to avoid...
The kinetics of CO 2 absorption into aqueous solutions N,N‐diethylethanolamine (DEEA), and N,N‐dimethylethanolamine (DMEA), their blends with monoethanolamine (MEA) have been studied in a stopped‐flow apparatus. experiments were carried out at the concentrations DEEA DMEA varying from 0.075 to 0.175 kmol/m 3 , respectively, that MEA ranging between 0.0075 0.0175 over temperature range 293–313 K. Two models are proposed interpret reaction blended amine systems results show model which...
A strategy for improving the capture of CO2 was developed through entropic effect by tuning geometric construction anion-functionalized ionic liquids. Several kinds liquids with amino group at para or ortho position were designed and applied CO2, which indicates that former exhibited both higher capacity lower enthalpy, resulting in efficient energy-saving capture. Viscosity measurements, spectroscopic investigations, quantum chemical calculations showed such a unique behavior originated...
Generally, amine group captures CO 2 according to 2:1 or 1:1 stoichiometry. Here, we report a kind of improved carbon capture using amino‐functionalized ionic liquids (ILs) through 1:2 A serial ILs various with basicity and steric hindrance anion were designed, prepared, applied in capture. Through combination absorption experiment, quantum chemical calculation, spectroscopic investigation calorimetric method, the results indicated that one could bind two proton transfer (PT) process...
In this work, the composite catalysts, SO 4 2 /ZrO /γ‐Al O 3 (SZA), with different ZrO and γ‐Al mass ratios were prepared used for first time carbon dioxide (CO )‐loaded monoethanolamine (MEA) solvent regeneration process to reduce heat duty. The characteristics five catalysts (three SZA two parent catalysts) of a 5 M MEA solution an initial CO loading 0.5 mol /mol amine at 98°C investigated in terms desorption performance compared those blank test. All characterized using X‐ray diffraction,...
The formation of bicarbonate ions in an amine solution during CO2 absorption results lowering the heat duty for solvent regeneration capture process because breakdown needs lowest energy input to release CO2. In this study, was conducted two mixed solvents consisting tertiary amines (1DMA2P (1 M) or MDEA M)) blended with MEA order determine both rate and capacity as compared alone. concentrations used study were (5 M), MEA–MDEA (5:1 molar ratio, 6 M total), MEA–1DMA2P total) at various...
The mass transfer performance of CO 2 absorption into blended N,N‐diethylethanolamine (DEEA)/ethanolamine (MEA) solutions was investigated using a lab‐scale absorber (H = 1.28 m, D 28 mm) packed with Dixon ring random packing. coefficient K G v , the unit volume rate Φ, outlet concentration (y CO2 ), and bottom temperature T bot in aqueous DEEA/MEA were determined over feed range 298.15–323.15 K, lean loading 0.15–0.31 mol/mol, wide liquid flow 3.90–9.75 m 3 /m ‐h, by inert gas 26.11–39.17...
In this work, industrial grade sepiolite (IG-SEP) was premodified with hydrochloric acid, and then (SEP) impregnated triethylenetetramine (TETA) to create a novel TETA functionalized SEP adsorbent. The effects of loading adsorption temperature on CO2 capacity, as well the isotherm cyclic regenerability were investigated.
