Abstract in another language

Proton, 13C, and 129Xe NMR were applied for characterizing the change of the tortuosity, the chemical structure of the coke, as well as the pore size during the deactivation and decoking of a commercial naphtha reforming catalyst (Pt/Re-Al2O3). All experimental evidence indicates that a full recovery of the activity of the clean catalyst is not achieved by the regeneration process, and that the quality of regeneration depends on the coke content reached during the deactivation/regeneration cycle.
