天然气水合物是在一定压力温度条件下,天然气中某些气体组分与水形成的一种复杂且不稳定的白色结晶固体.本文采用差示扫描量热法(DSC)测定天然气水合物的形成温度,使用十二烷基磺酸钠(SDS)作为促进剂.测试周期短,测得的甲烷水合物形成临界温度与理论值很接近.%Natural gas hydrate (NGH) is a complex and unstable white crystalline solid formed by interaction between some gas components and water under certain pressure and temperature. This paper measures the temperature of NGH formation by differential scanning calorimetry (DSC) using sodium dodecylsulphate (SDS) as accelerating agent. The experiment period of this method is short, and the measured temperature of NGH formation is very close to the theoretical temperature.
