Studies on pore systems in catalysts: XV. The influence of the geometrical factor on the t curve measured on aerosil

In a previous article of this series it was shown that the t curve measured on Aerosil greatly deviates from the common t curve. In this article we shall treat this phenomenon in more detail. From the nitrogen-sorption isotherms, measured on four different aerosils, the t curves are calculated. It i...

Description
Summary:In a previous article of this series it was shown that the t curve measured on Aerosil greatly deviates from the common t curve. In this article we shall treat this phenomenon in more detail. From the nitrogen-sorption isotherms, measured on four different aerosils, the t curves are calculated. It is shown that the magnitude of the deviations from the common t curve depends on the particle size of Aerosil. By calculations, based on geometrical and thermodynamic considerations, theoretical t values are obtained in perfect agreement with the experimental ones.
