Crystal growth of clathrate hydrate formed with H2 + CO2 mixed gas and tetrahydropyran

Molecular storage of ozone in a clathrate hydrate formed from an O3+O2+CO2 gas mixture.

Efficient Gas Selection and Storage Using Nanosise Cage Structures: A Theoretical Investigation on Hydrate Clathrate and Mackay Crystal

In this talk, I will discuss results from our group in the area of computational modeling using density functional theory for reversible hydrogen storage materials. The reversible hydrogen storage is an important area in the context of renewable energy and the reversibility places important challenge. We have studied doped magnesium hydrides as well as decorated metal organic frameworks (MOF). ...

Phase equilibrium and dissociation enthalpy for semi-clathrate hydrate of CO2+TBAB

The present work investigates equilibrium conditions and dissociation enthalpy of hydrates formed from CO2-TBAB(tetra-n-butylammonium bromide)-water mixtures. Differential Thermal Analysis (DTA) was used for Hydrate-Liquid-Vapour (H-L-V) equilibrium condition determination in a TBAB concentration range from 4.43 to 9.01 wt% and in a CO2 pressure range from 0.3 to 2.5 MPa. The results showed tha...

Evaluation of the Effect of Nonionic Surfactants and TBAC on Surface Tension of CO2 Gas Hydrate

Given that most of the gaseous constituents of industrial chimneys are usually carbon dioxide which is one of the most important greenhouse gases. It seems that the hydration process is one of the newest methods for the separation of this gas from gaseous mixtures. In the gas hydrate formation industry, in addition to disadvantages, there are some advantages such as gas separation, transmission...

NMR/MRI study of clathrate hydrate mechanisms.

Clathrate hydrates are of great importance in many aspects. However, hydrate formation and dissociation mechanisms, essential to all hydrate applications, are still not well understood due to the limitations of experimental techniques capable of providing dynamic and structural information on a molecular level. NMR has been shown to be a powerful tool to noninvasively measure molecular level dy...
