【摘要】 对由冰生成天然气水合物过程中的过饱和度和过冷度的作用进行了实验研究。结果表明 ,较大的过饱和度和过冷度提高了生成水合物的含气率 ,同时反应还存在一个最佳反应时间。提出冰转化为水合物的过程是一个包括气体的外扩散、产物层内扩散以及界面反应的过程更多还原

【Abstract】 The effects of supersaturation and supercool on ice conversion to natural gas hydrate was studied.The results show that higher degree of supersaturation and supercool accelerates the hydrate formation, and there exists an optimal reaction time.The theory of hydrate formation process consisting of the external diffusion, internal diffusion in production layer and reaction on interface was also given.更多还原
