Abstract

Four lithium metal precursors (LiNO3, CH3COOLi, LiOH, LiCl) have been used as promoters in Pt−Sn/Al2O3 catalysts to improve activity, selectivity and stability in a modeln-decane dehydrogenation reaction. Acidity, TPR and TPCO measurements have shown that the precursors affect the acid site distribution in the support, modify the reducibility and dispersity of Pt−Sn active species, coke lay-over patterns, stability and also selectivity for formation of monoolefins in the dehydrogenation ofn-decane.
