Abstract: This invention relates to a process for regenerating reprocessing of oxidation catalysts, which contain oxides of molybdenum, tungsten, copper and, if appropriate vanadium, by treatment with ammonia, a carboxylic acid or ammonium salt thereof and, if appropriate, hydrogen peroxide, with dissolution of the catalytically active metal components, evaporation of the water from the solution and heating of the resulting salt residue for activation.

Abstract: Cu is extracted from spent catalysts contg. Cu and/or oxides of Cu, Zn, Al and Cr which have been used for CO conversion, or methanol synthesis, by adjusting the mole ratio of ZnO/Al2O3 in the mixt. to 1:0.9 to 1:1.2 by addn. of ZnO and/or Al2O3, and heating the mixt. to at least 800 degrees C pref. 900-1100 degrees C for 1 hr before separating Cu from the other metals by dissolving in dilute nitric acid or an aq. soln. of an ammonium salt.
