Numerical Analysis of the Horvath–Kawazoe Equation — The Adsorption of Nitrogen, Argon, Benzene, Carbon Tetrachloride and Sulphur Hexafluoride
A previously proposed numerical procedure based on the Horvath–Kawazoe (HK) model for estimating the MPSD (micropore size distribution) from a single nitrogen adsorption isotherm was developed. The results of the calculation of MSPD for two synthetic carbons obtained from numerical studies using the...

description |
A previously proposed numerical procedure based on the Horvath–Kawazoe (HK) model for estimating the MPSD (micropore size distribution) from a single nitrogen adsorption isotherm was developed. The results of the calculation of MSPD for two synthetic carbons obtained from numerical studies using the modified procedure are presented and discussed. These allowed the evaluation of the distribution from a single adsorption isotherm of nitrogen, argon, benzene, carbon tetrachloride and sulphur hexafluoride. In addition, the nitrogen and argon adsorption potential distributions were calculated for the same carbons applying the HK and condensation approximation (CA) methods. Agreement between these two independent approaches was observed. Differences between the MSPD obtained from HK and from the Dubinin micropore filling model (using the CONTIN package) were observed and discussed. It was shown that the structural parameter of the Dubinin–Astakov equation had no significant influence on the MSPD curves obtained. |
