   Oct 28, 2020 · A relatively small number of guest molecules with a shorter induction time for pure guest hydrate nucleation can promote the formation of initial nuclei of a mixed hydrate. Detailed cage analysis shows that small guests such as CH 4 can induce the formation of more standard cages for mixture systems with either C 2 H 6 or C 3 H 8 systems ...

   Why are guest-host interactions important?

   • Therefore, fundamental understanding of these guest-host interactions is a key to controlling the structure-property relations for the different energy applications. The different and diverse compositions for inorganic clathrates compared to hydrates lead to very different applications.

   What are the guest atoms in a clathrate hydrate?

   • The guests are atoms, typically alkali and alkaline earth metals, such as Na, K, Ba, etc. As in the case of the clathrate hydrates, the host lattice of the inorganic clathrates is comprised of cages in which these guests reside. 2 Interactions between guest atoms and the framework may be ionic or covalent depending on the chemical composition.

   How many guest molecules are in a clathrate hydrate cage?

   • Typically, there is a maximum of one guest per cage, and the compounds are nonstoichiometric in that some cages can remain vacant in the clathrate lattice. Important to note here is that the guest molecules interact with the hydrate cage walls only via weak van der Waals forces. 1

   Aug 28, 2015 · In the case of clathrate hydrates (often simply referred to as “Hydrates”), the host is composed of hydrogen-bonded water molecules which are arranged in a three-dimensional crystalline lattice. 1 The guests that can be trapped within the water host lattice comprise small molecules, e.g., methane, carbon dioxide, hydrogen.
