天然气水合物又称可燃冰。二十世纪七十年代,美国地质工作者在海洋中钻探时,发现了一种看上去像普通干冰的东西,当它从海底被捞上来后,那些“冰”很快就成为冒着气泡的泥水,而那些气泡却意外地被点着了,这些气泡就是甲烷。据研究测试,这些像干冰一样的灰白色物质,是由天然气与水在高压低温条件下结晶形成的固态混合物。目前的科研考察结果表明,它仅存于海底或陆地冻土层内。纯净的天然气水合物外观呈白色,形似冰雪,可以像固体酒精一样直接点燃,因此,人们通俗、形象地称其为“可燃冰”。
Gas hydrate, also known as combustible ice. In the 1970s, when US geologists were drilling in the ocean, they found something that looked like ordinary dry ice. When it was taken from the sea floor, those “ice” quickly became brazen Bubbles of muddy water, and those bubbles are accidentally lit, these bubbles are methane. According to research tests, these gray-like substances like dry ice are solid mixtures of natural gas and water crystallized under high pressure and low temperature. The current research results show that it only exists in the seabed or continental frozen soil. Pure natural gas hydrate appearance is white, the shape of ice and snow, can be directly lit as solid alcohol, therefore, people popular, vividly call it “combustible ice.”
