Summary: This study focuses on improving the formation kinetics and hydrogen storage capacity of hydrogen hydrate using nano promoters. The results show that nano promoters can effectively enhance the formation kinetics of H2/THF hydrate, leading to a higher hydrogen storage capacity. Among the nano promoters, -SO3- @PSNS performs the best, surpassing conventional kinetic promoters in terms of effectiveness and applicability.

Summary: This study investigated the thermodynamics and kinetics of methane hydrate formation in the presence of cetyltrimethylammonium bromide (CTAB) solutions. The cage occupancy and hydration number of the hydrates were determined, showing a range of 3.1-3.6 and 5.9-6.1, respectively. CTAB was found to have no impact on the phase equilibria of methane hydrate, and the kinetic rate constants for different CTAB solutions were also determined. Additionally, large-scale reactor experiments demonstrated the ability of CTAB to promote hydrate formation.

Summary: In this study, the effect of two ionic liquids on the formation and dissociation of hydrates was investigated. The results showed that these ionic liquids were effective in inhibiting hydrate formation both thermodynamically and kinetically. The induction time and formation rate of hydrates were significantly increased in the presence of these ionic liquids compared to pure water. Additionally, the performance of the ionic liquids in hydrate inhibition increased with increasing alkyl chain length.

Summary: Coalbed methane recovery is crucial for coal mine safety, reducing greenhouse gas emissions, and economic benefits. Gas hydrate technology can effectively separate CH4 from N2-rich coal mine gas. The synergistic effect of sII hydrate promoters and amino acids was examined for enhancing hydrate formation kinetics, separation performance, and CH4 recovery. Amino acids showed significant promotion effects, particularly for the propane system, and improved kinetics by over 10 times. CP-amino acid systems demonstrated excellent separation performance, increasing CH4 content from 30% to 70%. THF-amino acid systems achieved the highest CH4 recovery of up to 50.27%. The impact of amino acids varied depending on the system, and two possible mechanisms, including interfacial tension alteration and amino acid hydrophobicity, were discussed. These insights provide a basis for optimizing the hydrate process for coalbed methane recovery and other applications.

Summary: Gas hydrate naturally forms in subsea beds and transportation pipelines with favorable conditions, while ionic liquids (IL) have emerged as novel inhibitors for gas hydrate formation and dissociation. This review focuses on thermodynamic and kinetic modeling of the gas hydrate/IL system, discussing inhibition aspects and the role of ILs. Future areas for modeling gas hydrate/IL systems and potential improvements are also highlighted.

Summary: This study demonstrates that the addition of pyrrolidine during methane hydrate formation can improve the thermodynamic stability of the hydrate, enhance formation, and achieve higher formation rates. Experimental results also show that pyrrolidine can achieve shorter induction times and faster rates of hydrate formation under more relaxed conditions.

Summary: The effects of ionic liquids (ILs) on CO2 hydrates were studied, and it was found that all five ILs could increase CO2 consumption and enhance water to hydrate conversion. [P2 4 4 4][PF6] and [P6 4 4 4][PF6] promoted CO2 hydrate nucleation, resulting in a slightly higher temperature for phase equilibrium and reduced induction times. On the other hand, [N2 2 2 2]Br, [N2 2 2 2][NTf2], and [N2 2 2 2][PF6] slowed down CO2 hydrate nucleation, leading to a lower temperature for phase equilibrium and prolonged induction times.

Summary: Carbon dioxide hydrate formation rate is improved by using different accelerator systems. The combination of nanographite-TBAB and SDS-TBAB shows better performance in reducing the nucleation time. TBAB shows the best nucleation amount, formation rate, and conversion rate among the single acceleration systems.

Summary: This study investigated the thermodynamic and kinetic mechanism of the polymorphic transformation of Puerarin, including solvent-mediated and solid-state transformations. The results showed that stirring rate and temperature facilitated the solvent-mediated transformation, while heating led to the formation of different anhydrates from PUEMH and PUEDH. The dehydration rate differed between the two hydrated forms due to varying hydrogen bond interactions, with different rate-limiting steps in the dehydration process.

Summary: Research shows that sodium lignin sulfonate (SLS) has little negative impact on hydrate formation and can actually increase the conversion rate of water into hydrate. The study also reveals the effects of SLS on different stages of hydrate formation for the first time, establishing a model to predict the influence of pressure on hydrate formation.

Summary: Hydrate-based technology has not been commercially applied due to issues such as formation conditions and slow reaction kinetics. This study investigated the impact of high thermal conductive metallic nanofluids, specifically silver (Ag) and copper (Cu), on the formation of CH4 and CO2 hydrates. The results showed that while Ag and Cu promoted CH4 hydrate formation, they either inhibited or had little influence on CO2 hydrates.
