This paper demonstrates the practicality of using unit cell volume as a tool to monitor the dealumination, and hence the deactivation of ZSM-5 zeolite in catalyst. This new tool developed combines the use of X-ray diffraction and Rietveld Refinment to provides valuable guidance for the development of ZSM-5-based additives for FCC application.
