Embodiment 1
[0014] Based on a total amount of 500g, use an electronic balance to weigh nano-graphite powder, sodium dodecylbenzenesulfonate and distilled water with a particle size of about 50nm at a ratio of 0.05%, 0.02%, and 99.3%, and add nano-graphite particles to the In the aqueous solution, use a magnetic stirrer to mechanically stir at a speed of 400rpm, and the stirring time lasts for 18min. After adding the surface dispersant SDBS, the stirred solution is stirred again with a magnetic stirrer at a speed of 600rpm, and the stirring time lasts for 25min. The liquid was ultrasonically dispersed for 15 minutes, and the dispersed liquid was mechanically stirred again at a speed of 800 rpm for 35 minutes. The prepared nanofluid package is ready for use.
[0015] This implementation case is carried out in a reactor with a volume of 500mL. The gas selected in the laboratory is carbon dioxide. The prepared nanofluid 250mL is added to the reactor through the liquid inlet system, and the te...
Embodiment 2
[0017] Based on the total amount of 500g, use an electronic balance to weigh nano-graphite powder, sodium dodecylbenzenesulfonate and distilled water with a particle size of about 50nm at a ratio of 1.5%, 0.08%, and 98.42%, respectively, and add the nano-graphite particles to the In the aqueous solution, use a magnetic stirrer to mechanically stir at a speed of 500rpm, and the stirring time lasts for 18 minutes. After adding the surface dispersant SDBS, the stirred solution is stirred again with a magnetic stirrer at a speed of 700rpm, and the stirring time lasts for 25 minutes. The liquid was ultrasonically dispersed for 20 minutes, and the dispersed liquid was mechanically stirred again at a speed of 800 rpm for 30 minutes. The prepared nanofluid package is ready for use.
[0018] This implementation case is carried out in a reactor with a volume of 500mL. The gas selected in the laboratory is carbon dioxide. 250mL of the prepared nanofluid is added to the reactor through th...
Embodiment 3
[0020] The preparation of the nanofluid is basically the same as in Example 1, except that the mass fraction of the nano-graphite powder is 1.5%, the mass fraction of sodium dodecylbenzenesulfonate is 0.02%, and water is the balance.
[0021] This implementation case is carried out in a reactor with a volume of 500mL. The gas selected in the laboratory is carbon dioxide. Add 250mL of nanofluid with a fraction of 0.02% into the reaction kettle, and control the temperature of the water bath at 6°C through the water circulation refrigeration system, and enter the air through the air intake system until the pressure in the kettle reaches 4MPa, and generate at constant volume at a speed of 350rpm Hydrate, hydrate crystal nuclei were observed after 140s.
