Dissociation of double hydrate and methane hydrate

AIP Conference Proceedings, 2019
A comparison of the dissociation of n-propanol double hydrate and methane hydrate at external air temperature 22 °C and at air pressure of 1 bar was carried out experimentally. The particles of the double hydrate showed a significantly higher growth rate in the reactor than particles of gas methane hydrate. Thus, alcohol is a promoter in the generation

Combustion of methane hydrates

Journal of Engineering Thermophysics, 2013
Gas hydrates of methane were obtained under the laboratory conditions, and their structural characteristics were determined there. Kinetics of methane hydrate dissociation in the air atmosphere was studied experimentally. The combined effect of high temperature and pressure gradients was studied and it was shown that in practice it is necessary to take

Hydrophobic hydration of methane

Molecular Physics, 1997
The method of neutron diffraction and isotopic substitution (NDIS) with H/D substitution on both the solute and the solvent was used to determine the hydration structure of a methane molecule (CM4, M = H or D) in terms of partial pair correlation functions g HM(r) and g OM(r).

Methane hydrate as a “new energy”

2019
Methane hydrate (MH) becomes a promising new energy in some countries including China and Japan due to its huge reservation. The key mission is to find the safe and efficient exploitation method. The exploitation processes will cause stress changes, which may induce submarine landslides and failures of engineering projects.

HYDRATES OF METHANE AND HYDROGEN

2019
Gas hydrates are icelike solids composed of guest molecules or atoms of gases trapped inside the cages formed within a crystalline host framework (clathrate) of hydrogenbonded water molecules. The report will mainly be devoted to various aspects of the formation and decomposition of methane hydrates, large deposits of which are found in permafrost and ...
