中文摘要：

利用可视化高压流体测试系统研究了甲烷-四丁基溴化氨(TBAB)水合物的分解条件,并根据物相平衡数据应用Clausius-Clapeyron方程计算了该水合物的分解热。结果显示:CH_4-TBAB共生水合物的相平衡压力的对数与温度的倒数为线性关系,其相平衡压力远低于甲烷水合物的相平衡压力,甲烷的存在提高了TBAB水合物的生成温度。CH_4-TBAB共生水合物的分解热远大于纯TBAB水合物的分解热,而且分解热的数值与TBAB的浓度有关。

英文摘要：

The dissociation heats for the hydrates of methane and TBAB were determined with Clausius-Clapeyron equation based on the hydrates phase equilibrium data and the phase equilibrium data were investigated by using the isothermal pressure search method for four components of TBAB aqueous solutions.The results show that hydrate dissociation heat is high than the single TBAB hydrate.The dissociation heat is related to the mass ratio of TBAB and the functional relation is same as Langmuir function.
