Department of Chemical Engineering, University of AmsterdamAbstract. TPD of n-nonane gives a micropore size distribution of micropores in the range of .4 to 2 nm. This method is independent of the shape of the pore entrances. It is proven that n-nonane fills these micropores. The Temperature Programmed Desorption patterns of five activated microporous carbons and three zeolites will be shown.The difference in adsorption behaviour of CO2 and SF6 at 273 K and of CH4 at 315 K on the carbons is explained with the aid of the obtained micropore size distributions.
