| Abstract: | The diffuse fluxes have been measured by using the steady state method, nitrogen and carbon dioxide are used for diffusion gas pair. The tortuositdy factors of non-poisoned and surface poisoned C207 catalyst are obtained. The values of tortuosity factor are 3.65 for non-poisoned catalyst and from 2.99 to 3. 11 for surface poisoned catalyst according to average pore size, 4.17 for non-poisoned catalyst and from 3. 45 to 3.71 for surface poisoned catalyst according to pore size distribution. |
