Comparison of Transport Characteristics and Textural Properties of Porous Material; the Role of Pore Sizes and Their Distributions

Original language description

Based on a study of a set of porous materials with wide range of mean pore radii (from 50 to 3000 nm) and mono- or bidisperse pore structure the comparison of obtained transport characteristics and textural properties is discussed. Structure characteristics relevant to transport processes were evaluated from multicomponent diffusion and permeation measurements. For data analysis the Mean Transport Pore Model (MTPM) based on Maxwell ? Stefan diffusion equation and Weber permeation law was used. Two standard methods - physical adsorption of nitrogen and mercury porosimetry (ASAP2010M and AutoPore 9200, Micromeritics, USA) were used for determination of textural properties. Results from liquid expulsion permporometry measurement that correspond to situation in industrial processes were also taken into account. For some porous materials transport characteristics obtained from permeation and diffusion analyses are shown in Table.
