Embodiment 1
[0043] The selected accelerator SM1 has the following components: graphene oxide concentration (wt) 0.1%, sodium chloride (NaCl) concentration (wt) 0.30%. Add deionized water and stir at 50°C for 70 minutes to prepare a graphene oxide dispersion. The experiment was done with methane gas at a temperature of 6.3°C, and the experimental procedure was the same as above. The experimental results are shown in Table 2. The experimental steps are the same as above.
