摘要

Process for the reactivation of a spent oxidic catalyst suitable for oxidation, ammoxidation and/or oxidative dehydrogenation of olefines and that contains a tellurium oxide and as active components mainly oxides of antimony and/or iron. The spent catalyst is mixed with a solid particulate tellurium compound or with a particulate, solid carrier material containing a tellurium compound.
