چکیده انگلیسی
The development of two different in-flow scanning reactors that could be successfully used for testing the activity of planar catalysts are presented. The first one, which allows stepwise scans, is composed by a reactor probe which is sealed over the planar system using a Teflon or Viton mask that also defines the reaction chamber volume. The presence of the sealing mask causes various problems that are solved with the second prototype. In this reactor a controlled leakage system is used instead of the Viton seal, which allows continuous scanning test on a reduced circular area (12.5 mm2). In this paper the results of preliminary tests over palladium based catalysts are presented in order to discuss the applicability of both reactors.
