最近,新华社播发了一条消息,报导了在我国南海发现了新型能源——“可燃冰”,从而使人们对“可燃冰”产生了极大的兴趣。 另类天然气 可燃冰顾名思义点火能燃烧,是一种非常规能源。它是天然气分子(除氢、氦和氖外)充填在水的晶体笼架中形成的冰状固体物,又叫(天然)气水合物或固体气。由于可燃冰中以甲烷(大于90％)为主,故也称甲烷水合物。充填甲烷的可燃冰1立方米可产出气164立方米和水0.8立方米,其能量密度是煤和黑色页岩的10倍左右,故是一种能量密度高的能源。
Recently, Xinhua News Agency broadcast a news report that found a new type of energy in the South China Sea - “combustible ice”, so that people have a great interest in “combustible ice.” Alternative natural gas flammable ice can ignite as the name implies, is an unconventional energy. It is a natural gas molecule (except hydrogen, helium and neon) filled in water crystal cage formed in the ice-like solid material, also known as (natural) gas hydrate or solid gas. As combustible ice methane (more than 90%) based, it is also known as methane hydrate. 1 cubic meter of methane-filled combustible ice can produce 164 cubic meters of gas and 0.8 cubic meters of water. Its energy density is about 10 times that of coal and black shale, so it is an energy source with high energy density.
