Methane clathrate (CH 4 ·5.75H 2 O) or (4CH 4 ·23H 2 O), also called methane hydrate, hydromethane, methane ice, fire ice, natural gas hydrate, or gas hydrate, is a solid clathrate compound (more specifically, a clathrate hydrate) in which a large amount of methane is trapped within a crystal structure of water, forming a solid similar to ice.
1 Δεκ 2023 · In this work, we determine the methane (CH 4) hydrate formation mechanism in the presence of a thermodynamics promoter, Cyclopentane (CP), and find that structure II (Str.II) CH 4 hydrate, as a metastable intermediate structure of the reaction, plays a quite significant role in encapsulating CH 4 molecules in some 5 12 6 4 cages (Str.II ...
14 Μαρ 2022 · Here, we have performed molecular dynamics simulations to clarify the nucleation path of methane hydrate. We demonstrated that methane gather with a three-body aggregate pattern corresponding...
1 Ιουλ 2021 · Here the authors comment on past interpretations and aim to provide a roadmap for developing a predictive theory of methane hydrate nucleation.
12 Μαρ 2021 · Methane hydrate is an ice-like solid composed of methane and water that is found in a cold, high pressure, layer (the HSZ) near the seafloor in the deep ocean. We modeled how methane hydrate forms in nature as sediment is deposited and buried with time.
1 Οκτ 2014 · Methane hydrate turns out to defy simple questions about whether it is an energy blessing or a climate curse, posing much larger puzzles about how global systems work and what their time frames...
22 Αυγ 2019 · Methane hydrate solubility increases with temperature and decreases with pressure and salinity (Henry et al., 1999). The hydrate-water capillary pressure, the pressure difference between the hydrate and liquid water, can increase the methane hydrate solubility in pores (Figure 2 b).
