Unusual PT dependence of thermal conductivity for a clathrate hydrate

Heat Transfer Related to Gas Hydrate Formation/Dissociation

“…They found the influence is a complex interplay among particle size, effective stress, porosity, and fluid-versus-hydrate filled pore spaces, not only porosity. With respect to temperature effect, many studies found that hydrates exhibit a glass-like temperature dependence of thermal conductivity (Andersson and Ross, 1983;Handa and Cook, 1987;Krivchikov et al, 2005Krivchikov et al, , 2006Ross et al, 1981;Ross and Andersson, 1982;Tse and White, 1988). Among these studies, the works of Krivchikov et al (2005Krivchikov et al ( , 2006 are interesting as they found that both methane and xenon hydrates show crystal-like temperature dependence below 90 K, while exhibiting glass-like behavior above 90 K. The effect of pressure has also been investigated by many groups (Andersson and Ross, 1983;Rosenbaum et al, 2007;Waite et al, 2007).…”

Observation of Frost Heave of THF Clathrate Hydrate on Porous Glass Powder

“…From the perspective of recent environmental and industrial concerns, the structures of various clathrate hydrates (Mak and McMullan 1965;Gough and Davidson 1971;Sloan 1990) and their thermal properties at equilibrium (Ross et al 1981;Leaist et al 1982;Handa et al 1984) have been clarified. Since the formation and dissociation of clathrate hydrate are greatly affected by the solute, the dependence of the solute on the phase equilibrium conditions has been investigated (de Roo et al 1983).…”

“…B. durch Zersetzung). Interessant ist nicht nur der geringe Wert der Wärmeleitfähigkeit, sondern auch ihr Temperaturverlauf, der demjenigen von Gläsern oder amorphen Festkörpern ähnlicher ist als dem eines kristallinen Festkörpers [11].…”
