| Description |
ZSM-5 zeolites having three types of extra lattice alumina, namely acid insoluble extra
framework alumina (AlEFAL), amorphous alumina (AMAL) and binder alumina (BNAL)
were studied. Microcalorimetric acid strength distribution studies indicated the presence of
very strong acid sites in the sample containing AlEF AL. Presence of amorphous alumina did
not show any significant influence on acid strength distribution. But, the amount of poly
aromatic compounds formed in n-heptane aromatization reaction over this catalyst is more,
indicates the occurrence of non-shape selective surface reactions on this alumina. Presence of
binder alumina showed the positive effect on stability in activity of n-heptane aromatization
reaction. A common phenomenon observed with all the catalysts is the fast deactivation of
strong acid sites.
Key words: ZSM-5, Extra-lattice Aluminum, Deactivation and Aromatization.
