摘要:

利用多孔介质水合物实验装置研究了含水活性炭体系中水合物储存甲烷的特性。活性炭的大比表面和孔隙水有利于水合物的形成,而其孔隙则不利于水合物的形成。本文以活性炭作为水合物形成的载体,实验研究了甲烷水合物的形成过程。结果 表明,含水活性炭体系中水合物结晶成核时间缩短,含水活性炭储存甲烷的能力随着实验压力的升高而增大。在一定的压力和温度条件下,含水率在1左右时,活性炭的储气能力最强。

Abstract:

Methane storage in hydrates with wet active carbon was investigated using test rig for hydrate in porous materials.Specific surface area and pore water of active carbon promote hydrate formation,but the pore goes against hydrate formation.Taking active carbon as the carrier,the experiment studied methane hydrate formation in wet active carbon.The result shows that crystallization nucleation time is shorter in wet active carbon than in pure water.Methane storage capacity in wet active carbon increases while experimental pressure increases.When wetting ratio(water mass/active carbon mass) is about 1,it will achieve the maximum value of the methane storage capacity in wet active carbon.
