  • Supported oxidative dehydrogenation catalyst
    Patent number: 8846996
    Abstract: The present invention provides a process for the manufacture of an efficient and robust catalyst for the oxidative dehydrogenation of paraffins to olefins, preferably lower C2-4 paraffins. The present invention provides a process for the preparation of an oxidative dehydrogenation catalyst of C2-4 paraffins to olefins comprising comminuting: from 10 to 99 weight % of a mixed oxide catalyst of the formula VxMoyNbzTemMenOp, wherein Me is a metal selected from the group consisting of Ta, Ti, W, Hf, Zr, Sb and mixtures thereof; with from 90 to 1 weight % of an inert matrix selected from oxides of titanium, zirconia, aluminum, magnesium, yttria, lantana, silica and their mixed compositions or a carbon matrix to produce particles having a size from 1 to 100 microns and forming the resulting particles into pellets having a size from 0.1 to 2 mm.
