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 gama-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 Evaluation of micropore volume and mesopore surface area in microporous-mesoporous samples is presented.
