摘要：
Catalytic dehydrogenation of propane over alkali promoted Pt/HZSM-5 is investigated. Among the catalysts tested in this work, 1%Li-Pt/HZSM-5 exhibits a much better improvement in propene selectivity. Reactionpathway on the catalyst is postulated as a synergetic effect of reversed hydrogenspillover and controlled acidity of the catalyst. Another function of Li in thesuppressing of hydrogenolysis activity by Pt is also observed.
