(1) In completion, this paper presents new ( p, , T) measurements in the critical region of methane. The measurements were carried out very close to the saturation line on isotherms from 180 K up to the critical temperature T c = 190.551 K for the vapour and from 186 K up to the ...
The critical pressure (Pc) and critical temperature (Tc) of shale gas depend on the characteristic pore size because of the importance of fluid–rock interactions in the matrix. This size dependency is neglected in highly permeable formations, where gas composition is only implemented because the ...
Studies on the Physical Adsorption Equilibria of Gases on Porous Solids over a Wide Temperature Range Spanning the Critical Region—Adsorption on Microporo... Adsorption equilibria of nitrogen and methane on microporous ( < 2 nm) activated carbon were measured for a wide temperature range (103-298...
Ignition of methane air mixtures by frictional heating is relevant to LNG transportation and mine safety. In this paper, I review experimental and theoretical work concerned with methane air ignition by hot surfaces. Of main concern is the influence of surface size, orientation, temperature-time his...

6.2.Crystal structures of NiO, CuO, and Cu2O. Schematic below shows relation between the Cu valence and oxygen coordination in copper oxides. Thecritical temperatureof square-planar copper oxides is not very high, 43K at the highest (Smithet al., 1991). This is because no hole doping has ...
Critical constants of pure fluids (as important reference data in constructing vapour-liquid phase diagrams and basic input of various estimation methods) were determined for systems of non-spherical Kihara molecules; values of the critical temperature, density, compression factor and pressure of fluids...
The amplification of oxidation achieves higher efficacy of organics degradation, which is highly dependent on pH value, H2O2 concentration, temperature, and catalyst dosage. It is well known that both H2O2 and lactic acid are over-expressed in tumor, providing primary requirements to apply Fenton/...
The anomalous behavior of the isochoric heat capacity of a mixture of methane, pentane and heptane is studied experimentally in the vicinity of the liquid-vapor critical point in the cases when (a) the critical temperature T c approaches the tricritical point T TCP and (b) the critical tempera...
Although it is generally accepted that we know the most about the critical temperature and the least about the critical density, the discussion shows that it is the limiting value of the critical density that we know with the most certainty....
