Fundamental Investigations of Heterogeneous Catalysis Using Isotopic Transient Kinetic Analysis
EMSL Project ID
18902
Abstract
This project will apply a unique capability at PNNL for heterogeneous catalysis R&D employing isotopic transient kinetic analysis (ITKA) techniques with mass spectroscopic and in-situ transmission FTIR analyses. The apparatus will enable an in-situ probe of adsorbed reactants/intermediates/products on catalyst surfaces, as well as measuring gas phase concentrations to elucidate reaction mechanisms and kinetic parameters. The resulting data will be interpreted and applied to develop microkinetic models for catalytic reactions of importance to the US?s future energy, environment, and economic security. Particular attention will be given to reactions of interest to the President?s hydrogen economy initiative (e.g., fuel reforming, water-gas shift chemistries, partial oxidation of CO under hydrogen-rich environments-PROX, methane activation chemistries, and additional systems as they develop).
