Dehydrocyclization of n-octane: H/D exchange and reversible adsorption for a Pt-Sn-SiO{sub 2} catalyst
- Univ. of Kentucky, Lexington, KY (United States)
With a Pt-SiO{sub 2} catalyst n-octane underwent dehydrocyclization in the presence of D{sub 2} or with an equimolar mixture of n-octane-d{sub 0} and n-octane-d{sub 18} without a measurable extent of H/D exchange in the unconverted n-octane. When similar experiments were conducted with a Pt-Sn-SiO{sub 2} H/D exchange occurred. The results suggest that tin functions to decrease the strength of chemisorption of n-octane at 482{degrees}C so that adsorption is reversible in contrast to the irreversible adsorption for a Pt-SiO{sub 2} catalyst. The presence of tin allows H/D exchange to occur in the unconverted n-octane. 49 refs., 8 figs.
