✦ Synopsis

An experimental method for determination of porous solid texture was proposed and verified. The method is based on unsteady permeation of single gases in a porous medium. Transport parameters characterizing porous materials were determined by fitting the experimental data to the theoretical transient responses by minimizing the objective function. Confidence limits of the transport parameters were evaluated on the base of the Beale criterion. Results were discussed in terms of different mechanisms of mass transport. Advantages of this technique were demonstrated for three porous catalysts of different textures.
