In this paper we will have a detailed look at a numerical procedure that allows the estimation of the acid site strength Ε½ . distribution using a single temperature programmed desorption TPD experiment. The possibility of estimating these parameters is of paramount importance in the determination of
The acidity of H-form zeolites which include mordenite, ZSM-5, Y-faujasite, and those modified by cation exchange or deahrmination was measured by temperature-programmed desorption (TPD) of NHp. Ammonia was adsorbed at 373 K to eliminate the contribution of very weak acid sites and improve the spect
