R. Gomez et al., EFFECT OF TIN PRECURSOR ON THE CATALYTIC PROPERTIES OF PT-SN AL2O3 SOL-GEL PREPARED CATALYSTS/, JOURNAL OF SOL-GEL SCIENCE AND TECHNOLOGY, 8(1-3), 1997, pp. 847-849
Tin-alumina supports were prepared by cogelation of aluminum tri-sec-b
utoxide and tetrabutyltin or tin tetrachloride. Aqueous or acetone pla
tinum solutions were used for impregnation. The results show that the
specific surface area and the acidity of the catalysts were only sligh
tly modified by the metal precursors used. On cyclohexane dehydrogenat
ion and n-hexane conversion, high selectivity to olefins and low crack
ing products were detected.
