Influence of THF and THF/SDS on the Kinetics of CO2 Hydrate Formation Under Stirring

Hydrate-based gas separation is a potential technology for CO 2 recovery and storage, its products can be used fire prevention control in mines. Promoters are often employed to accelerate or moderate hydrate formation. In this study, experiments were performed examine the effects of different concentrations thermodynamic promoter tetrahydrofuran (THF) kinetic sodium dodecyl sulphate (SDS) on formation under stirring. The results showed that THF significantly shortens induction time hydrates; however, because occupies large cavity structure, it also reduces absorption rate. SDS has no obvious effect hydrates, but increase storage density Using together consumed more than using alone pure water. peak consumption rate was 2.3 times system. efficiency improved by including both SDS, which maximized total uptake.
