Abstract: KF-Zn3(PO4)2 catalyst was found to be effective for isobutane oxidative dehydrogenation into isobutene. The effects of O2 concentration in feed gas on isobutene yield and selectivity were discussed. The modification of zinc phosphate by potassium fluoride leads to the formation of a new compound KF-Zn3(PO4)2 and surface basic sites, the catalytic performance of which is thus improved.

Key words: Oxidative dehydrogenation, Isobutane, Isobutene, KF-Zn3(PO4)2catalyst
