Abstract: Process for regenerating spent multimetal oxide oxidation catalysts from catalytic gas-phase oxidations of lower organic compounds, which catalysts, unspent, contain as base constituents the elements Mo, W, V and Cu in oxide form, by the action of oxidising agents and of solubilising aqueous ammonia containing added acetic acid and/or the ammonium salt thereof and subsequent drying and calcination in which, within the process, the content of the metallic constituents is quantitatively determined and supplemented to the respective original value.

Abstract: PCT No. PCT/EP94/03345 Sec. 371 Date Apr. 19, 1996 Sec. 102(e) Date Apr. 19, 1996 PCT Filed Oct. 11, 1994 PCT Pub. No. WO95/11081 PCT Pub. Date Apr. 27, 1995In a process for the preparation of catalytically active poly-metal oxide materials containing Mo and V, a catalyst intermediate is calcined at from 300 DEG to 450 DEG C. in a gas atmosphere which, in addition to inert gases and/or steam, consists of from 0.5 to 4% by volume of O2 and, averaged over the calcination time, from 1 to 8% by volume of NH3.
