Then, a gas adsorption coefficient is determined in the laboratory, and the gas content is calculated.
The new proposed approach was effectively applied to compute transport coefficients of gas adsorption in porous solids derived from EIS data.
where [[delta].sub.ij] is the Kronecker symbol; G is the coal shear modulus (Pa), G = E/2 (1 + u); K is the bulk modulus of coal (Pa), K = E/3 (1 - 2u); E is Young's modulus of coal (Pa); u is Poisson's ratio of coal; a is the Biot coefficient; and [[epsilon].sub.s] is the gas adsorption strain.
This was because the micropore volume not specific surface area was a more important factor for gas adsorption on carbon materials.
In order to determine the effect of gas adsorption on the conductivity of the proposed Ti[O.sub.2] material after adsorbing typical gases of lung cancer patients on its surface, the frontier molecular orbital theory was conducted.
The gas adsorption capacity of coal is one critical issue for the estimation of a coalbed methane reservoir, coalbed methane production, and carbon dioxide sequestration with enhanced CBM recovery [3].
While gas adsorption also occurs during the process of gas drainage, which always produces certain swelling stresses and then leads to swelling deformation of coals, and so gas seepage is a fluid-solid coupling dynamic process.
The gas adsorption and desorption behaviors during gas-sensing measurements are demonstrated below, which perhaps open a promising new opportunity for specific gas analyte recognition.
To investigate gas adsorption capacity and pore size distribution of shale rocks, high-pressure methane adsorption and low-pressure nitrogen or carbon dioxide adsorption experiments are conducted, respectively.
