The Effect of La Doped on V2O5/γ-Al2O3 Catalyst for Activity in the Dehydrogenation of Isobutane

Abstract

Abstract: V₂O₅/γ-Al₂O₃ is a new catalyst for the isobutane dehydrogenation.It was found that the dehy-drogenation activity of catalysis and the action of coke can be improved by adding appropriate La.Thestructure and surface state of La-doped V₂O₅/γ-Al₂O₃ catalysts were characterized by FTIR, BET, TG,TPRand TPR.The result showed that the changes of dispersion and reduction property of active compo-nents were quite obvious after adding La.

Key words: Isobutane, Dehydrogenation, Lanthanum oxide, Vanadium pentaoxide
