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 mm(2)). In this paper the results of preliminary tests over palladium based catalysts are presented in order to discuss the applicability of both reactors.

Abstract
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 mm(2)). In this paper the results of preliminary tests over palladium based catalysts are presented in order to discuss the applicability of both reactors.| File | Dimensione | Formato | |
