FT-IR studies of the adsorption of nitriles show that the external surface of H-FER, H-MFI, and H-MOR carries terminal silanols and strong Lewis sites. Terminal silanols present wide heterogeneity with respect their Brønsted acidity also in relation to the zeolite structure. Bridging Si-(OH)-Al exist at the internal channel surface only of...

The catalytic activity of the zeolite HZSM5 in n-butene conversion was investigated under conditions similar to those of a commercial process for skeletal isomerization. The catalyst was found to be very active in n-butene conversion, but selectivity to isobutene was low due to a predominance of cracking, coking, and oligomerization side...
