“…Moreover, the adsorption parameters of CO 2 determined by the LCM-based adsorption measurement device in this work compare well to values reported in literature [9][10][11][12] , i.e., the adsorption capacity, adsorption enthalpy and adsorption entropy reported for CO 2 in MFI-type zeolites vary in the range of 2.1-3.8 mmol g …”

We present a high-temperature and high-pressure gas adsorption measurement device based on a high-frequency oscillating microbalance (5 MHz langatate crystal microbalance, LCM) and its use for gas adsorption measurements in zeolite H-ZSM-5. Prior to the adsorption measurements, zeolite H-ZSM-5 crystals were synthesized on the gold electrode in the center of the LCM, without covering the connection points of the gold electrodes to the oscillator, by the steam-assisted crystallization (SAC) method, so that the zeolite crystals remain attached to the oscillating microbalance while keeping good electroconductivity of the LCM during the adsorption measurements. Compared to a conventional quartz crystal microbalance (QCM) which is limited to temperatures below 80 °C, the LCM can realize the adsorption measurements in principle at temperatures as high as 200-300 °C (i.e., at or close to the reaction temperature of the target application of onestage DME synthesis from the synthesis gas), owing to the absence of crystalline-phase transitions up to its melting point (1,470 °C). The system was applied to investigate the adsorption of CO 2 , H 2 O, methanol and dimethyl ether (DME), each in the gas phase, on zeolite H-ZSM-5 in the temperature and pressure range of 50-150 °C and 0-18 bar, respectively. The results showed that the adsorption isotherms of these gases in H-ZSM-5 can be well fitted by Langmuir-type adsorption isotherms. Furthermore, the determined adsorption parameters, i.e., adsorption capacities, adsorption enthalpies, and adsorption entropies, compare well to literature data. In this work, the results for CO 2 are shown as an example.

“…Many methods are employed to separate CO2 from entering into atmosphere, but sorption method [3] was found to be more economical and simplest [4]. Zeolites, persovskites, hydrotalicites, soda lime, polymeric membranes, fcu-MOF based rare-earth metals and also metal oxides like lithium zirconates, lithium potassium zirconates, sodium metasilicates, etc., are used as a sorbents to capture or separate CO2 from the atmosphere [5][6][7][8]. Usually the metal oxides used as adsorbents for the removal of CO2 from the flue gas and atmosphere, forms respective solid metal carbonates [9][10][11].…”

Tailoring Metal–Organic Frameworks for CO₂ Capture: The Amino Effect

et al. 2011

View full text Add to dashboard Cite

Carbon dioxide capture from processes is one of the strategies adopted to decrease anthropogenic greenhouse gas emissions. To lower the cost associated with the regeneration of amine-based scrubber systems, one of the envisaged strategies is the grafting of amines onto high-surface-area supports and, in particular, onto metal-organic frameworks (MOFs). In this study, the interaction between CO(2) and aliphatic and aromatic amines has been characterized by quantum mechanical methods (MP2), focusing attention both on species already reported in MOFs and on new amine-based linkers, to inspire the rational synthesis of new high-capacity MOFs. The calculations highlight binding-site requisites and indicate that CO(2) vibrations are independent of the adsorption energy and monitoring them in probe-molecule experiments is not a suitable marker of efficient adsorption.
