Characterizing Supported Metal Catalysts
The downstream petroleum industry employs a supported metal catalyst for reforming (increasing aromatic content for increased octane value). Hydrogenation reactions employ similar active metals, as do automotive emission catalysts. It's possible to quantitatively determine the extent of gas-accessible reactive sites, and dispersion, using the adsorption of suitable reactive gases, i.e. chemisorption.
• Metal area, dispersion, nanocluster size
• Sample preparation
• Selecting the right adsorbate
• Vacuum-volumetric (manometric) gas sorption method and technology
• Dynamic flow gas sorption method and technology
• Irreversible and reversible chemisorption, spillover, stoichiometry
In this webinar, you will learn how chemisorption is used to characterize supported metal heterogeneous catalysts, and the relative benefits of the two alternative experimental approaches. The capabilities of automated instruments to make these measurements will be presented.
Trainer: Dr. Martin Thomas
Dr. Thomas, Anton Paar QuantaTec’s Chief Scientist, has more than 37 years of experience in powder and porous materials characterization, 27 of those with Quantachrome Instruments before Anton Paar’s acquisition in 2018. Dr. Thomas graduated from the University of Birmingham (UK) with a Master’s degree in analytical chemistry followed by a PhD in physical-inorganic chemistry. He is named co-inventor on eight patents relating to porous solids and their characterization, and is co-author of “Characterization of Porous Solids and Powders: Surface Area, Pore Size and Density” (published by Springer).
