Characterising porous carbonaceous materials using the new methods: An attempt for estimation of micropore size distribution function from adsorption isotherm of nitrogen and benzene

The study presents the analysis of adsorption data of nitrogen and benzene adsorption onto four microporous carbons. The most advanced methods of porosity characterisation, namely: the method of Do and co-workers (called Do), DFT, CONTIN, HK, and the methods basing on Dubinin's potential theory of adsorption are put to use. It is shown, that the similarity between obtained results depends on the dispersion of microporosity of carbonaceous material, and if this dispersion is relatively high, all methods lead to very similar pore size distribution curves
