What are gas hydrates? | U.S. Geological Survey - USGS.gov
Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures. Methane is the most common gas present in gas hydrate, although other gases may also be included in hydrate structures, particularly in areas close to conventional oil and gas reservoirs.
Clathrate hydrate - Wikipedia
Clathrate hydrates, or gas hydrates, clathrates, or hydrates, are crystalline water-based solids physically resembling ice, in which small non-polar molecules (typically gases) or polar molecules with large hydrophobic moieties are trapped inside …
Gas Hydrates - Department of Energy
Gas hydrates consist of molecules of natural gas (the chief constituent of natural gas; methane) enclosed within a solid lattice of water molecules. When brought to the earth's surface, one cubic meter of gas hydrate releases 164 cubic meters of natural gas.
What are gas hydrates? - NOAA Ocean Exploration
Gas hydrates are ice-like crystalline structures that form when a low-density gas, like methane, ethane, or carbon dioxide, combines but does not chemically bond with water and freezes into a solid under low temperature and moderate pressure conditions.
Methane clathrate - Wikipedia
Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
Gas Hydrates - Primer | U.S. Geological Survey - USGS.gov
2018年3月19日 · Gas hydrate is an ice-like crystalline form of water and low molecular weight gas (e.g., methane, ethane, carbon dioxide). On Earth, gas hydrates occur naturally in some marine sediments and within and beneath permafrost. Gas hydrates have also been inferred on other planets or their moons.
Gas Hydrates | U.S. Geological Survey - USGS.gov
2018年11月2日 · Gas hydrates are naturally occurring ice-like combinations of natural gas and water that have the potential to provide an immense resource of natural gas from the world's oceans and polar regions.
What are Gas Hydrates? – Centre for Gas Hydrate Research
Gas hydrates (or clathrate hydrates) are ice-like crystalline molecular complexes formed from mixtures of water and suitably sized ‘guest’ gas molecules. The water (host) molecules, upon hydrogen bonding, form lattice structures with several interstitial cavities.
Gas hydrates - AAPG Wiki
2015年1月6日 · Gas hydrates (also called gas clathrates) are icelike, crystalline solids composed of natural-gas molecules, principally methane, trapped in rigid crystalline cages formed by frozen water molecules.
Gas Hydrate in Nature - USGS
What is Gas Hydrate? Gas hydrate is a naturally occurring, ice-like substance that forms when water and gas combine under high pressure and at moderate temperatures.
