碳化铝与水反应合成甲烷水合物的实验研究

 利用自行设计的高压气水合物实验装置，通过碳化铝与水反应成功合成了甲烷水合物。实验结果表明，碳化铝与水反应合成甲烷水合物的方法有效地解决了传统甲烷水合物模拟实验中甲烷气体引入问题；同时，碳化铝与水反应产生的甲烷及沉淀物能较好地模拟海洋环境中水合物形成的自然条件，为实验模拟甲烷水合物研究提供了一种新方法。利用此方法，对甲烷水合物合成与分解温度、压力条件及动力学过程进行了初步研究。

Experimental Study of Methane Hydrate Prepared through Reaction of Al_4C_3 with H_2O

Methane hydrate is successfully prepared through the reaction of Al4C3 and H2O using a laboratory designed high pressure hydrate apparatus.Experimental results indicate that this method is an effective solution to introduce CH4 in the synthetic experiments of methane hydrates,and the pressure-temperature formation conditions of the methane hydrate approach the natural situation.In addition,the products of the reaction of Al4C3 and H2O can simulate the real formation process of methane hydrate in the ocean e...
