Evaluation of the Two-Dimensional Performances of Low Activity Planar Catalysts: Development and Validation of a True Scanning Reactor.

Abstract:

:The development of a scanning reactor for planar catalysts is presented here. With respect to other existing models, this reactor is able to scan catalysts even with low turnover frequencies with a minimum sensed circular area of approximately 6 mm in diameter. The downstream gas analysis is performed with a quaprupole mass spectrometer. The apparatus performances are presented for two different reactions: the hydrogenation of butadiene over palladium films and the oxidation of CO over a gold/titania catalyst. With the final setup, true scans in both X and Y directions (or even in a previously defined complex directional pattern) are possible within a scan speed ranging from 0.1 to 5.0 mm/min. Finally, this apparatus aims at becoming a valuable tool for high throughput and combinatorial experimentation to test patterned active surfaces and catalytic libraries.
