A method is described for the regeneration of an Fe-Mo catalyst by grinding the exhausted catalyst and then by processing it with chem. reagents to increase activity and selectivity. Either distd. H2O or aq. solns. of ammonium oxalate, of oxalic acid, or of their mixt., or an aq. soln. of NH4NO3 and of an ammonium molybdate with pH lower than 2, or a 0.1-50% aq. soln. of HNO3 is used as the reagents. A MoO3 in the form of a sol. compd. can be added to the aq. soln. of reagents.
