| Zusammenfassung: | Described is a regeneration method for exhausted catalysts containing crystalline, porous materials with a MFI type structure, which cannot be regenerated only through mortar. This method consists of carrying out a thermal treatment followed by a nitrogen, organic base treatment in hydrothermal conditions, preferably with an acid chosen from: citric acid, tartaric acid or formic acid. |
