Abstract

A new experimental method for the measurement of catalyst surface area of supported catalyst has been developed using selective physisorption. The desorption characteristics of a gas are studied separately on the catalyst, the support, and the supported catalyst carrying out thermal desorption experiments in a continuous flow sorptomer. Differences in the coverage vs. temperature curves, obtained from the thermal desorption experiments, are a measure of the selectivity of the physisorbing gas, and allow calculation of the fraction of total surface area occupied by the catalyst. Two systems have been studied utilizing the thermal desorption with carbon dioxide as adsorbate: potassium carbonate/carbon black and silver/alumina. The experimental technique allows for straightforward calculation of the catalyst area.
