Abstract
Four lithium metal precursors (LiNO3, CH3COOLi, LiOH, LiCl) have been used as promoters in Pt-Sn/Al2O3 catalysts to improve activity, select ivity and stability in a model n-decane dehydrogenation reaction. Acid ity, TPR and TPCO measurements have shown that the precursors affect t he 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 dehydrogenati on of n-decane.
