In May 2017 a group of researchers led by the University of Texas at Austin Jackson School of Geosciences took to the Gulf of Mexico to retrieve samples of methane hydrate, a potential future...
6 Σεπ 2016 · Methane hydrate: fire, ice, energy. Found near the ocean floor and beneath Arctic permafrost, methane hydrate is a mysterious icy substance that burns when lit and holds vast amounts of potential energy.
Researchers brave enough to abseil down into the craters have found elevated levels of methane in the water pooling at the bottom, suggesting the gas may be bubbling up from below. One leading ...
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.
2 Ιουν 2017 · Abstract. Widespread methane release from thawing Arctic gas hydrates is a major concern, yet the processes, sources, and fluxes involved remain unconstrained. We present geophysical data documenting a cluster of kilometer-wide craters and mounds from the Barents Sea floor associated with large-scale methane expulsion.
15 Φεβ 2021 · Addition of gaseous water up to the hydrate state requires approximately 180 g of the HE, and the charge initiating detonation in the real hydrate increases to 1.35 kg of the HE, which testifies to comparatively low explosion hazard of acetylene hydrates.
The kinetics of methane hydrate formation, after the onset of nucleation, were studied by using a semibatch stirred-tank reactor at 274-284 K over a pressure range of 3-10 MPa. The formation kinetics depend on the interfacial area, pressure, temp., and degree of supercooling.
