Hydrothermal-fluid Drying Synthesis of New V-O-Al Catalyst for the Dehydrogenation of Isobutane

Abstract

Abstract: The V-O-Al catalyst was prepared by hydrothermal-fluid drying synthesis method and was tested in the dehydrogenation of isobutane to isobutene. The catalysts were characterized by means of XRD, ESR, TPR and BET. The V-O-Al catalyst, derived from hydrothermal synthesis and possessing a higher vanadia dispersion in the alumina and larger surface area, especially showed a better catalytic activity and marked stability than the supported vanadium oxide catalyst.

Key words: V-O-Al catalyst, Hydrothermal synthesis, Fluid drying, Isobutane, Isobutene, Dehydrogenation
