High throughput monitoring of catalytic characteristics usin TAP-approach

A new approach to high throughput monitoring of non-steady-state catalytic activity characteristics based on the combination of catalyst preparation is presented. The approach combines in a single apparatus an atomic beam deposition (ABD) system with a temporal analysis of products reactor system and a new methodology of non-steady-state kinetic characterization. It is focused on establishing direct, reproducible correlations between changes in surface composition and changes in catalyst activity. The ABD technique was demonstrated by the deposition of different amounts of Pd and PdO on quartz particles, and the reactivity of the resulting materials toward the CO oxidation reaction was then characterized. The theoretical foundations of this approach and methodology were presented. State-by-state catalyst kinetic screening of catalytic properties was illustrated using examples of hydrocarbon selective oxidation over oxide catalysts and CO oxidation over platinum Pt containing catalysts. This is an abstract of a paper presented at the 8th World Congress of Chemical Engineering (Montreal, Quebec, Canada 8/23-27/2009).
