摘要：

The catalytic reforming of n-heptane over Pt/Al//2O//3, Sn/Al//2O//3 and Pt-Sn/Al//2O//3 has been studied. Distinct activity and selectivity changes have been observed during the operation of each catalyst. The use of the bi-metallic catalyst results in the control of coke deposition, increased stability and improved aromatics yield. These effects can be interpreted in terms of a change of properties of Pt that results from interaction with Sn, involving electronic modification, ensemble effects or both.
