摘要：

HZSM-5 zeolites with and without template having SiO2/Al2O3 ratio = 28 have been synthesised. The acidity of the samples was measured by stepwise temperature programmed desorption of ammonia and calorimetric measurement of ammonia adsorption. The difference in catalytic activity of these samples for aniline alkylation and cumene cracking have been discussed from the point of view of total acidity and relative Bronsted and Lewis acid sites.
