Controlled hydrothermal treatment of H-ZSM-5 at 500Β°C causes a transformation of framework into non-framework aluminium, as indicated by means of cation exchange and IR spectroscopy. After treatment with nitric acid, partial extraction of non-framework aluminium was observed. The non-framework alumi
