A New Method to Calculate the Absolute Amount of High-Pressure Adsorption of Supercritical Fluid
In the paper we developed a new method to determine the absolute amount of adsorption. This method relies on the excess adsorption isotherm and the density profile in the pore of one material. To compute the density profile and decrease complex calculation of obtaining the absolute amount of adsorpt...

| description | In the paper we developed a new method to determine the absolute amount of adsorption. This method relies on the excess adsorption isotherm and the density profile in the pore of one material. To compute the density profile and decrease complex calculation of obtaining the absolute amount of adsorption we introduced Simplified Local-Density (SLD) model. A few of appropriate parameters were acquired to calculate the density profile through SLD models the adsorption isotherm of methane on AX-21 activated carbon. In these parameters specific surface area and slit width is close to the true value of the AX-21 activated carbon. And we found SLD can accurately simulate the adsorption of supercritical methane on activated carbon and the precision rises up as temperature raises. The corresponding application of our method on adsorption of methane on AX-21 activated carbon was introduced at different temperature from 233 to 333K. The absolute isotherms of adsorption calculated by our method are reasonable when compared to other results. |
