The V₂O₅/γ-Al₂O₃ for dehydrogenation of isobutane was found to have a high catalytic activity under reaction conditions of 590℃, GHSV=1 000 h^-1 and atmospheric pressure. The structure of the catalyst was characterized by means of XRD, UV-V is and BET technique. The results indicated that the dehydrogenation behavior of the catalyst was in correlation with the dispersion and the state of vanadia on the catalyst surface. Chemical composition and physical state of vanadia on the catalyst surface are affected by the kind of support, the loading of vanadium and calcination temperature as well.
