Conclusions The reason could be assigned to the suitable acidic and alkaline strength and quantity distributions on the surface of Cluster Al2O3. Meanwhile, smaller-particle MoS2 has more edge-exposed active sites, whi...
At present, DES has been widely used in the removal of acidic gases such as SO2, CO2 and NOx, and shows good absorption and recyclability. What's more, DES, as an effective solvent for selective absorption of H2S, has gradually attracted the attention of academia and industry. However, ...
Increasing the methane partial pressure results in a pronounced decrease of the solubility of the acidic component. This is line with the results of the experiments carried out by Addicks (2002). He measured the solubility of CO2 and CH4 in aqueous MDEA at pressures up to 200 bar. At the ...
However, in the case of weak acidic conditions (pH < 7.0), the fluo- rescence turn-on signal is marginally lower, which was commonly observed in nucleophilic-reaction probes29–33. To test the biological applicability of the dual-reactable probe 1, we examined whether 1 can be used ...
Nevertheless, the simple construction of composite heterojunctions, in which α-Fe2O3 is direct contact with the acidic gas (H2S) in the gas–solid reaction system, can lead to poisoning and deactivation. Against this backdrop, it is feasible to use COFs with high stability as a shell and ...
(H2O) ≥ 80% is improved after oxidative absorption of H2S and discharge of volatile HCl from the acidic mixtures. Furthermore, as shown inFigure 5c,d, homogeneous mixtures atx(H2O) = 90% after oxidative-absorption of H2S become colourless due to the complete reduction of FeCl3·2H2O and ...
Figure 1 reveals that the Nf-TNPP-film-based OWG sensor is more sensitive and more stable toward EDA and H2S than the TNPP-film-based sensor. This is ascribable to electrostatic interactions between the four -NO2 functional groups on the porphyrin and the -SO3− groups of the Nafion ...
Lower reboiler duties and higher-than-expected mass transfer have been observed, at the expense of an intrinsic viscosity increase (for some but not all solvents), which will have to be addressed. Among water-lean solvents, ionic liquids are gaining more interest for both CO2 and H2S removal,...
