The clathrate hydrate process for post and pre-combustion capture of carbon dioxide.
One of the new approaches for capturing carbon dioxide from treated flue gases (post-combustion capture) is based on gas hydrate crystallization. The basis for the separation or capture of the CO(2) is the fact that the carbon dioxide content of gas hydrate crystals is different than that of the flue gas. When a gas mixture of CO(2) and H(2) forms gas hydrates the CO(2) prefers to partition in ...
متن کاملEnthalpy of Dissociation of Simple and Mixed Carbon Dioxide Clathrate Hydrate
The enthalpy of dissociation is an important property of clathrate hydrates. Through it is possible to obtain some conclusions about the microscopic structure formed. It can be obtained by direct methods of measurement or estimated by indirect methods. However, the inherent difficulties of direct methods influence the accuracy of this methodology. Given this, the direct or indirect methods show...
متن کاملPreservation of carbon dioxide clathrate hydrate in the presence of trehalose under freezer conditions
To investigate the preservation of CO2 clathrate hydrate in the presence of sugar for the novel frozen dessert, mass fractions of CO2 clathrate hydrate in CO2 clathrate hydrate samples coexisting with trehalose were intermittently measured. The samples were prepared from trehalose aqueous solution with trehalose mass fractions of 0.05 and 0.10 at 3.0 MPa and 276.2 K. The samples having particle...
متن کاملEncapsulation kinetics and dynamics of carbon monoxide in clathrate hydrate
Carbon monoxide clathrate hydrate is a potentially important constituent in the solar system. In contrast to the well-established relation between the size of gaseous molecule and hydrate structure, previous work showed that carbon monoxide molecules preferentially form structure-I rather than structure-II gas hydrate. Resolving this discrepancy is fundamentally important to understanding clath...
متن کاملLaboratory infrared reflection spectrum of carbon dioxide clathrate hydrates for astrophysical remote sensing applications
We present 1–5 lm IR reflectance spectra of CO2 clathrate hydrates acquired under temperature and pressure conditions representative of the icy moons’ surfaces. The IR reflectance spectrum of the CO2 clathrate hydrates is similar to the water ice IR reflectance spectrum except for two main absorption bands corresponding to the CO2 guest molecule at 2.71 and 4.28 lm (3693 and 2334 cm!1). The spe...
