Zeolites are microporous aluminosilicates that are commonly used as catalysts and adsorbents in many applications. Acid site characterization of a zeolite is crucial to gauge and optimize it for a wide variety of different catalytic activities.

In this webinar, from Micromeritics Instrument Corporation, different types of zeolites were explored to characterize the acid sites such as ZSM-5 with different SiO2/Al2O3 ratios, mordenite, faujasite and ferrierite. Temperature Programmed Desorption technique on the AutoChem 2930 provides a simple and reproducible mean to qualitatively analyze solid acids. Using different basic probes, TPD allows obtaining insights on Lewis and Bronsted acid sites.
- Acid site characterization of zeolites
- Impact of SiO2/Al2O3 ratio on acid site strength
- Heat of desorption from first order kinetics.
- Lewis and Bronsted acid sites of zeolites (data pending)
