  • Metal oxide powders, their mixtures, metal mixed oxide powders, their mixtures and their use in catalytic dehydrogenation of hydrocarbons
    Patent number: 5053580
    Abstract: Metal oxide powders comprised of Cr(III) oxide, Ti(IV) oxide, V(V) oxide, or mixtures of these, or metal mixed oxides comprised of Cr(III) oxide and Ti(IV) oxide and V(V) oxide, or their mixtures. They have BET surfaces of 5-50m.sup.2 /g and mean particle diameters of 25-350 nm and are useful to increase conversion and selectivity in the manufacture of mono-olefins by catalytic dehydrogenation of saturated hydrocarbons. The metal oxide powders are produced from mixtures of the vaporized metal compounds chromyl chloride, titanium tetrachloride, and vanadyl chloride, in the presence of certain gases by laser pyrolysis.
    Type: Grant
    Filed: May 7, 1990
    Date of Patent: October 1, 1991
    Assignee: Veba Oel Aktiengesellschaft
    Inventors: Bernhard Schramm, Jurgen Kern, Harald Schwahn, August-Wilhelm Preuss, Klaus Gottlieb, Hartmut Bruderreck
