  • Ammoxidation catalysts for fluidized/moving bed reactors
    Patent number: 6200926
    Abstract: Solid catalysts suited for the fluidized/moving bed catalytic ammoxidation of alkanes comprise an active catalytic phase having the empirical formula (I): VSbaSnbTicFedEeOx  (I) in which E is an element which provides an oxide of rutile structure or an element which, in combination with V, Sb, Sn, Ti, Fe and/or with another element E, provides a phase of rutile or trirutile structure, or a solid solution of rutile structure, a is a whole or fractional number equal to or greater than 0.
