【摘要】 天然气水合物 (NGH)是天然气与水在低温高压条件下形成的笼形物 ,亦称可燃冰。在冻土带和海洋中已发现大量天然气水合物 ,是清洁燃料的后续天然资源 ,但开采技术尚不成熟。由于 1m3 天然气水合物在常温下可释放约 1 6 4m3 的天然气和 0 .8m3 的水 ,因此合成天然气水合物 ,可实现天然气的固态运输 ,更便于在天然气汽车上的储存。本文介绍天然气水合物的基本性质及其人工合成研究取得的进展更多还原

【Abstract】 Natural gas hydrate (NGH), known also as flammable ice, is a clathrate compound formed by natural gas and water under conditions of low temperature and high pressure. Great quantity of natural NGH was discovered in frozen earth and beneath seawater, which is a succeeded natural source of clean fuels. However, its exploitation is not yet on schedule due to technical difficulty. Artificial synthesis of natural gas hydrate is, on the other hand, an important topic of research. As many as 164 m 3 natural gas can be released from 1 m 3 NGH; therefore, NGH provides a compact way of transportation or storage of natural gas, which would be a great progress in the NGV technology. The fundamental property of NGH and the progress made in the experiments of artificial synthesis of NGH is presently introduced.更多还原
