Advancing Catalyst Characterization: Discovering the Power of Autosorb 3300

This in-person workshop introduces the fundamentals of physisorption and chemisorption and demonstrates their combined use to study catalyst deactivation. A platinum-on-alumina catalyst serves as a case study to highlight the advantages of cyclic adsorption measurements performed entirely within a single instrument, without removing the sample cell.

A catalyst is characterized at different stages of its life cycle—fresh, after propane dehydrogenation (via TPX), and after regeneration by temperature-programmed oxidation (TPO). Alternating physisorption, reaction, and regeneration steps provides complementary structural and chemical information, enabling in situ monitoring of surface area, metal dispersion, and deactivation phenomena.

This integrated approach offers a practical and largely unmatched strategy for comprehensive, in situ catalyst characterization across its full operational lifetime.


Key takeaways: 

  • Learn the fundamentals of physisorption and chemisorption and how each technique provides insight into catalyst properties
  • Explore how TPX and TPO techniques can be used to investigate catalyst reaction, deactivation, and regeneration
  • Discover how cyclic measurements can be performed on a a single instrument without removing the sample cell
     

Who should attend: 

This workshop is ideal for catalyst researchers, scientists, and engineers looking to gain deeper insight into catalyst performance, deactivation, and regeneration.

Brian Rodenhausen

Dr. Brian Rodenhausen is the Principal Application Scientist in the Particle and Porous Materials Characterization group at Anton Paar USA. He has over a decade of experience teaching users the theory and practice of analytical instruments, as well as advising them on the design of experiments and interpretation of results. His research background focused on label-free characterization of adsorbate layers at the solid-liquid interface. He received his Ph.D. in chemical engineering from the University of Nebraska-Lincoln (UNL) and did post-doctoral work at UNL and the Leibniz Institute of Polymer Research in Dresden, Germany. 

Ben Le Monnier

Dr. Ben Le Monnier is the chemisorption application specialist at the QuantaTec subsidiary of Anton Paar. He received his PhD of chemistry from Ecole Polytechnique Federale de Lausanne (EPFL), Switzerland, and did a post-doctoral work at Johns Hopkins University, in the group of Prof. Michael Tsapatsis. He recently shifted from academia to industry and now focuses on supporting all aspects of chemisorption instrumentation at Anton Paar QuantaTec.
