    Abstract: Process for the catalytically oxidative dehydrogenation of alkyl aromatics or paraffin hydrocarbons to the corresponding alkenyl aromatics or olefins by means of a redox catalyst (oxygen vehicle) in which in a first reaction stage the alkyl aromatic or paraffin hydrocarbon (educt) is dehydrogenated on a titanium dioxide carrier in the absence of molecular oxygen with a catalyst of a reducible metal oxide selected from the oxides of Bi, V, Ce, Fe, In, Ag, Cu, Co, Mn, Pb, Sn, Mo, Sb, As, W or their mixtures, whereby the catalyst is reduced, and in a second reaction stage the reduced catalyst is reoxidised by an oxidising agent.
