Abstract

In this paper, CO2 adsorption isotherms at 273 K are measured on five commercial carbonaceous adsorbents using volumetric method and their pore size distributions are determined and compared using DA, DS and HK MODELs. The results show that although the average pore diameter obtained from these models are almost the same, these models show different pore size distributions. Then obtained results from HRTEM images of one of samples and these model results are compared. The results also show that the average error for HK, DA and DS MODELs are 2.04, 2.73 and 1.42, respectively. Thus, DS MODEL is introduced as the best model for determination of pore size distribution, and DA MODEL gets the third rank.
