Abstract
Integrated laser and electron microscopy was applied to study individual fluid catalytic cracking catalyst particles deactivated according to an industrially relevant protocol.
New insights have been obtained by correlating Brønsted acidity changes, visualized using fluorescence microscopy, with structural transformations in the zeolite and matrix components, as observed with electron microscopy.
