Using Temperature Programed Analysis for Acid Site Characterization of Solid Acids

Editorial Checklist Reviewed

​​​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)
