Abstract (en)
[origin: DE19636884A1] The invention concerns a process for the heterogenocatalytic oxidative gaseous phase dehydrogenation of alkyl aromatics or aliphatics (educts) to form the corresponding alkenyl aromatics or olefins. In a first reaction step, the educt is dehydrogenated with a bismuth-containing redox catalyst (oxygen carrier) in the absence of molecular oxygen, and, in a second reaction step, the reduced catalyst is reoxidized with an oxidizing agent. The reaction steps are chronologically or spatially decoupled, and at least one reducible bismuthate (5) on a basic or neutral carrier is used as the bismuth-containing catalyst. The invention further concerns Ba-bismuthate (5) having the composition Ba9Bi3O14 as novel substance.
