摘要：
We developed a new method to determine the absolute amount of adsorption. This method relies on the excess adsorption isotherm and density profile in the pore of one material. The simplified local density (SLD) model was introduced to compute the density profile and simplify the complex calculation of obtaining the absolute amount of adsorption. The SLD can accurately simulate the adsorption of supercritical methane on shale. The corresponding application of our method on the adsorption of methane on shale and AX-21 activated carbon was introduced. The absolute isotherms of adsorption calculated with our method were reasonable when compared to results using other methods.
