A process for preparing an antimony-containing metal oxide catalyst, comprising the steps of calcining at about 500 DEG to 1,000 DEG C. a metal oxide composition containing, as essential elements, antimony and at least one element selected from the group consisting of iron, cobalt, nickel, manganese, uranium, tin and copper, impregnating the calcined oxide composition with a tellurium-containing solution, drying the impregnated composition, and calcining the dried composition at about 400 DEG to 850 DEG C., wherein the tellurium-containing impregnating solution is a homogeneous, stable solution containing tellurium and at least one element selected from the group consisting of molybdenum and tungsten. Thus process is also useful for the modification of existing metal oxide catalyst of low performance and the reactivation of existing deteriorated metal oxide catalyst. |
