Sensitivity Analysis of Computations of the Vapor-Liquid Equilibria of Methane + Methanol or Glycols at Gas Hydrate Formation Conditions [PDF]

open access: yes, 2019
The Soave-Redlich-Kwong (SRK-EOS) and Peng-Robinson (PR-EOS) equations of state are used often to describe the behavior of pure substances and mixtures despite difficulties in handling substances, like water, with high polarity and hydrogen bonding. They

Rapid Joule‐Heating‐Induced Non‐Equilibrium Exsolution in Perovskite Oxides for Enhanced Photothermal CO2 Methanation

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Rapid Joule heating induces Ni—Fe exsolution from perovskite oxides, forming Ni–Fe/oxide heterointerfaces that enhance photothermal CO2 methanation activity and selectivity. Achieving selective CO2 methanation under photothermal conditions requires catalysts capable of maintaining non‐equilibrium interfacial states that balance reduction and oxidation ...

Potentiale und Risiken der Nutzung von Methan aus Methanhydraten als Energieträger [PDF]

open access: yes, 2009
Marine and permafrost-based methane hydrates are the largest existing fossil carbon resource, whereby the marine deposits far outweigh the terrestrial ones.

Correlation Between the Molecular Structure of Metal‐Supporting Ligands and Catalysis in the Oxygenase‐Mimicking Immobilized Metal Complex Catalysts

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
The correlation between the structures of metal complexes immobilized in the mesopores of hydrophobically modified silicate supports was examined in relation to the catalytic activities toward C‐H oxidation. On the alkene oxidation with H2O2, the iron catalyst bearing bis(imidazolyl)methane ligand promotes allylic oxidation, whereas the mononuclear ...

Experimental Verification of Methane Replacement in Gas Hydrates by Carbon Dioxide

open access: yesChemical Engineering Transactions, 2013
If the conversion of methane hydrate to carbon dioxide hydrate with the net recovery of methane could occur, this would be quite attractive as an innovative method of both methane production and carbon dioxide storage.

Push–Pull Ynamines and Push–Pull Ynamides: Synthesis, Structure, Reactivity, and Application

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Push–pull ynamines and push–pull ynamides, which carry an EWG and an amino or amido group as EDG, are highly interesting classes of EDG‐EWG alkynes that have been intensively studied due to their exceptional reactivity. In this review, the synthesis, structure, reactivity, and application of push–pull ynamines, push–pull ynecarbamates, push–pull ...

In situ apparatus for the study of clathrate hydrates relevant to solar system bodies using synchrotron X-ray diffraction and Raman spectroscopy

open access: yes, 2015
Clathrate hydrates are believed to play a significant role in various solar system environments, e.g. comets, and the surfaces and interiors of icy satellites, however the structural factors governing their formation and dissociation are poorly ...
