摘要
采用恒压法、利用全透明蓝宝石釜及配套系统，考察了分解温度（245．15～271．15K）、生成压力（5．5～7．0MPa）、冷冻时间、搅拌对甲烷水合物分解率的影响。结果表明：甲烷水合物适宜的生成条件为3．2℃、压力6．5MPa、静态、冷冻时间为4h左右，甲烷水合物的适宜储运条件为常压、温度控制在-5℃左右。
The kinetics of methane hydrate decomposition was studied using sapphire cell apparatus at constant pressure. The effect of dissociation temperature ranging from 245.15 to 271.15 K, formation pressure ranging from 5.5 to 7.0 MPa, freezing time and stirring on the dissociaton percentages of methane hydrate is investigated. The results indicated that the fitting fomation condition of methane hydrate is 271.35 K,6.5 MPa, static state and freezing time is about 4 h. The condition of storing methane hydrate is at atmospheric pressure,about 268.15 K .
