冰点以下甲烷水合物等压分解实验研究

Experimental Study on the Isobaric Decomposition of Methane Hydrate

开展了甲烷水合物在2.25MPa、2.08MPa和1.88 MPa 3种压力和不同温度条件下等压分解实验,研究温度驱动力对甲烷水合物分解过程及其自保护效应的影响。实验结果表明,在等压分解过程中,温度推动力ΔT对甲烷水合物的分解产生较大影响,当温度推动力ΔT>|T0|时,分解速率与ΔT具有正相关关系;当ΔT≤|T0|时,甲烷水合物存在明显的自保护效应,分解速率与ΔT的关系不明显。

Experiments on methane hydrate isobaric decomposition were carried out with different temperatures under 2.25MPa,2.08MPa and 1.88MPa.The effect of temperature driving force on the decomposition process and self-preservation of the methane hydrate was discussed.During the isobaric decomposition of methane hydrate,the effect of temperature driving force on the decomposition rate can be classified into two parts.If the temperature driving force ΔT>|T0|,there s a positive correlation between decomposition ra...
