Experimental Verification of Methane Replacement in Gas Hydrates by Carbon Dioxide

Chemical 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.

Methane Hydration‐Shell Structure and Fragility

Angewandte Chemie, 2018
AbstractThe influence of oily molecules on the structure of liquid water is a question of importance to biology and geology and many other fields. Previous experimental, theoretical, and simulation studies of methane in liquid water have reached widely conflicting conclusions regarding the structure of hydrophobic hydration‐shells.

Comparative Study of Methane Hydrate Formation and Dissociation with Hollow Silica and Activated Carbon

Chemical Engineering Transactions, 2018
Natural gas hydrates are ice-like crystalline compounds and non-stoichiometric, and methane is trapped inside the water cages of the hydrates. In recent years, the hydrates have received much attention for natural gas storage and transportation. However,

Tandem Electrolysers for High‐Efficiency CO2‐to‐Acetate Conversion Driven by Full‐Spectrum Solar Energy

Carbon Energy, EarlyView.
A full‐spectrum solar‐driven tandem electrolysis system enables efficient CO2‐to‐acetate conversion by spectrally splitting sunlight and coupling high‐temperature SOEC CO2‐to‐CO electrolysis with ambient CO reduction. The integrated design achieves a solar‐to‐acetate efficiency of 15.8%, demonstrating effective energy‐quality matching for solar carbon ...

Hydroprocessing of synthetic kerosene over a non‐sulphided Ni/Al2O3 catalyst: Impact of alcohols and ketones on alkene conversion

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Synthetic jet fuel containing non‐petroleum‐derived kerosene can be produced from synthetic kerosene obtained through processes that include a hydroprocessing step. The potential use of non‐sulphided (reduced) nickel supported on alumina (Ni/Al2O3) was evaluated as an alternative to sulphided catalysts to saturate alkenes in sulphur‐free ...
