The internal structure of Fluid Catalytic Cracking (FCC) catalyst particles was investigated using confocal fluorescence microscopy. Inhomogeneously distributed, micron-sized zeolite domains were visualized. When laboratory deactivated FCC catalyst particles were studied using the same technique, a clear decrease in fluorescence intensity and thus reactivity of the zeolite domains was observed.
