Formulating formation mechanism of natural gas hydrates. [PDF]

open access: yesSci Rep, 2017
A large amount of energy, perhaps twice the total amount of all other hydrocarbon reserves combined, is trapped within gas hydrate deposits. Despite emerging as a potential energy source for the world over the next several hundred years and one of the ...

The lithological characteristics of natural gas hydrates in permafrost on the Qinghai of China [PDF]

open access: yesScientific Reports, 2022
The environment is seriously threatened by the methane emitted as permafrost melts. Studying deposits of natural gas hydrates that include methane is therefore important.

Proposal of experimental device for the continuous accumulation of primary energy in natural gas hydrates

open access: yesEPJ Web of Conferences, 2017
Hydrates of the natural gas in the lithosphere are a very important potential source of energy that will be probably used in the coming decades. It seems as promising accumulation of the standard gas to form hydrates synthetically, stored, and disengage ...

A Thermal Chemical Reaction System for Natural Gas Hydrates Exploitation

open access: yesFrontiers in Energy Research, 2022
The methodology of using CO2 to replace CH4 to recover the natural gas hydrates (NGHs) is supposed to avoid geological disasters. However, the reaction path of the CH4–CO2 replacement method is too complex to give satisfactory replacement efficiency ...
