Publikováno v: Chemical communications (Cambridge, England). 56(82)

The incorporation of ammonia inside methane clathrate hydrate is of great interest to the hydrate chemistry community. We investigated the phase behavior of methane clathrate formed from aqueous ammonia solution. Ammonia's presence decreases methane

Selective trapping of CO2 gas and cage occupancy in CO2–N2 and CO2–CO mixed gas hydrates

Autor: David Talaga, Françoise Damay, Claire Petuya, Sarah Desplanche, Arnaud Desmedt

Publikováno v: Chemical Communications. 54:4290-4293

Hydrate-based CO2 trapping from CO2–N2 and CO2–CO gas mixtures is shown by Raman spectroscopy – the results are of interest for new separation and capture technology. A better trapping efficiency is measured for low CO2 concentrations and N2-ba

Guest Partitioning and Metastability of the Nitrogen Gas Hydrate

Autor: Françoise Damay, Jean-Luc Bruneel, Claire Petuya, Arnaud Desmedt, Bertrand Chazallon

Publikováno v: The Journal of Physical Chemistry C. 122:566-573

Gas clathrate hydrates or gas hydrates are made of H-bonded water molecules forming cages, within which gaseous (guest) molecules are encapsulated. The formed clathrate structures, which may be metastable, depend on the nature and on the partitioning

Guest Partitioning in Carbon Monoxide Hydrate by Raman Spectroscopy

Autor: Arnaud Desmedt, Claire Petuya, David Talaga, Françoise Damay

Publikováno v: The Journal of Physical Chemistry C. 121:13798-13802

Gas hydrates are inclusion compounds composed of a H-bonded water network forming cages, inside of which gaseous (guest) molecules are encapsulated. Depending on the nature and partitioning of the guest molecules, various types of clathrate structure
