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
