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.
