摘要：

Catalyst extrudate in 3D: Through the use of tomographic energy dispersive diffraction imaging it is possible to obtain detailed three-dimensional insight into the metal oxide distribution inside a catalyst extrudate during its preparation. The picture shows such a 3D map of an extrudate along with examples of the detector signal for two different locations in the catalyst. (Graph Presented). © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
