| Description
| - Evaluation of micropore volume and mesopore surface area in microporous-mesoporous samples is presented. A series of mechanical mixtures of microporous zeolite NaY, and mesoporous gama-alumina was used for verification of the applicability of the (three-parameter) modified BET equation. The nitrogen adsorption isotherms (77 K) were analyzed by the modified (three parameters) BET equation and compared with the independent textural information obtained a) from t-plots (with the standard isotherm of nonporous alfa-alumina and the standard isotherms of Lecloux-Pirard) and b) by subtracting the isotherm of the parent NaY from mixed sample isotherms. Similarly, nitrogen adsorption isotherms of rutile samples with micropores blocked by n-nonane, from the literature were tested. For illustration, the failure of classic (two-parameter) BET equation for microporous-mesoporous samples is demonstrated.

- Za účelem ověření a důkazu správného vyhodnocení texturních vlastností (objemu pórů a specifického povrchu) mikro-mesoporézních materiálů byla připravena série směsných vzorků obsahujících mikroporézní zeolit NaY a mesoporézní gama-aluminu. Adsorpční izotermy dusíku (při 77K) byly analyzovány pomocí tříparametrové BET rovnice a získané výsledky (texturní vlastnosti) byly porovnány s nezávislými výsledky z t-plotů (za využití standardní izotermy alfa-aluminy a Lecloux-Pirarda) a odečtením izotermy zeolitu NaY od izoterem směsných vzorků. Porovnáním výsledků bylo rovněž demonstrováno chybné využití klasické BET rovnice k vyhodnocení texturních vlastností mikro-mesoporézních materiálů. (cs)
