【摘要】 通过在显微镜下观测加入3A分子筛粉末后的四氢呋喃(THF)-水体系的水合物生成过程,测量水合物生成时水合物相的界面移动速度.实验结果表明:在不同温度下水合物界面的生长速度都具有一致的规律,而且随温度变化不大,最大值约为1.1μm/s;同时界面生长速度随着反应进行而慢慢降低.更多还原

【Abstract】 Visual observation of the THF hydrate formation process with 3A molecular sieve was made at normal atmosphere and below zero temperature by microscope,and the moving velocity of THF hydrate interface was measured.The results indicate that the velocity has consistent rule under different temperatures and it has not big change along temperature’s change,the maximum velocity is approximately 1.1 μm/s;also the interface growth velocity reduces slowly with the reaction carries on.更多还原
