OXIDATION CATALYST Russian patent published in 2010 - IPC B01J23/20 B01J23/28 B01J27/57 C07C5/333 

FIELD: process engineering.

SUBSTANCE: invention relates to oxide catalysts for catalytic processes of hydrocarbon oxidative dehydration, in particular to oxidation catalysts. Oxidation catalyst for catalytic processes of hydrocarbon oxidative dehydration based on oxides of transition metals or mixes thereof selected from the group comprising Mo, V, Te, Nb of empirical formula Mo_aV_bTe_cNb_d, where a, b, c, d are gram-atomic proportions of corresponding elements, represents a geometrically structured solid calcinated structure with content of lattice oxygen not below 0.4 mmole of O₂/g and containing the components in the following molar ratios: molybdenum (a) - >1.00-1.50; vanadium (b) - 0.20-2.00; tellurium (c) - 0.20-1.50; niobium (d) - 0.01-1.50.

EFFECT: yield of product not lower than 1000 g per kg of catalyst at high conversion (approx 30-50%) and selectivity not worse than 95-97%.
