| 제목 | Inhibition of CO2 Hydrate by Piperidinium Ionic Liquids |
| 초록 | The phase equilibrium conditions of CO2 hydrates were examined in the presence of morpholinium and piperidinium ionic liquids (ILs) with a mass fraction of 0.1. The equilibrium conditions were in the ranges of (274.6 to 281.2) K and (1.80 to 3.95) MPa. The addition of ILs shifted the hydrate equilibrium conditions to a higher pressure and lower temperature region compared to the hydrate formed from pure water. Piperidinium and morpholinium ILs showed similar inhibition effects in the higher temperature range ≥ 278.5 K, whereas at lower temperature piperidinium ILs had a slightly better inhibition effect than morpholinium ILs. The anionic species also affected the hydrate inhibition effectiveness. Smaller anions, i.e., Br‒, had a slightly better inhibition effect than the bigger ions of BF4‒ This was supported by Korea National University of Transportation in 2016 |
