| 摘 要： | 利用二氧化碳水合物小型实验装置分别在恒容和恒压条件下,研究了机械搅拌对二氧化碳气体溶解的影响以及温度与水-气比对二氧化碳水合物形成和储气密度的影响。通过实验结果发现,机械搅拌对二氧化碳的溶解有非常明显的促进作用,可以在3 min内完成溶解过程,促进溶解作用好于添加剂SDS。研究还发现,反应温度越低,二氧化碳水合物的生成速率越快,总的储气量越大,而水-气比越大,储气密度越小。在实验压力3 MPa、反应温度273.55 K的条件下,1体积的水生成水合物后可储存157体积的二氧化碳。

| Abstract: | The characteristics of carbon dioxide dissolution by mechanical stirring were investigated experimentally in a high-pressure reactor.The effects of temperature and water-gas proportions on hydrate formation under the conditions of constant volume or pressure were discussed.The results showed that stirring can promote the dissolution rate of carbon dioxide considerably.By which,the process can be completed in three minutes,while the additive SDS does not work obviously.Also,it can be found that lower reactio... |
