Broad-line 'H NMR and 'H MAS NMR were used to determine the geometry of the Bransted acidic sites in zeolites H-ZSM-5. The signals obtained correspond to bridging hydroxyl groups in Si-OH-Al arrangements with an H-Al distance of 0.246-0.252 nm. The concentration of hypothetical SiOHSi groups must be
A zinc-modi®ed ZSM-5 catalyst was prepared by a solid-state reaction between zinc dust and H-ZSM-5. The resulting catalyst is as active for the aromatization of ethane as zinc-modi®ed ZSM-5 prepared by impregnation.
