摘要：
An attempt has been made to reveal the relation of adsorption characteristics of hydrogen on supported Pt catalyst (Pt/Al2O3) and on the same catalyst modified with adsorbed tin (Pt-Sn/Al2O3), together with die state of metals and the activity of these catalysts in propane dehydrogenation. The positive effect of modification of Pt/Al2O3 catalyst with adsorbed tin on selectivity of propane dehydrogenation was attained by an increase in hydrogen coverage. This prevented die destruction of propane and shifted the process toward dehydrogenation.
