Coke deposition and chemisorption results observed with a low surface area alumina support, raise the question of whether studies at high metal loadings are pertinent to the lower metal loadings which are used in commercial platinum-tin reforming catalysts. Because of the significance of this question, the current study was undertaken using a high area [gamma]-alumina as the support. A 0.3 wt% metal loading, supported on Cab-O-Sil, was also studied on the premise that complexing of tin by the support would be minimal. 5 refs., 2 figs., 1 tab.
