Web5 dec. 2024 · Clathrates are a class of compound that consist of a cage of molecules that can trap gases, such as methane, in a solid form. For methane, the most important "cage" is one that is made of water … Methane clathrates are common constituents of the shallow marine geosphere and they occur in deep sedimentary structures and form outcrops on the ocean floor. Methane hydrates are believed to form by the precipitation or crystallisation of methane migrating from deep along geological faults. Meer weergeven Methane clathrate (CH4·5.75H2O) or (8CH4·46H2O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a Meer weergeven The nominal methane clathrate hydrate composition is (CH4)4(H2O)23, or 1 mole of methane for every 5.75 moles of water, corresponding to 13.4% methane by mass, although the actual composition is dependent on how many methane molecules fit … Meer weergeven Since methane clathrates are stable at a higher temperature than liquefied natural gas (LNG) (−20 vs −162 °C), there is some interest in converting natural gas into clathrates (Solidified Natural Gas or SNG) rather than liquifying it when transporting it by Meer weergeven Methane hydrates were discovered in Russia in the 1960s, and studies for extracting gas from it emerged at the beginning of … Meer weergeven Methane clathrates are restricted to the shallow lithosphere (i.e. < 2,000 m depth).
