This invention concerns catalysts comprising a molybdenum compound of formula I, II, III, IV or V I V MoA O II NiMo B O III VNi Mo C O IV CoNi Mo D O V VNi Co Mo E O wherein: A is at least one cation selected from the group consisting of cations of: Cr, Sb, Co, Ce and Pb; B is at least one cation selected from the group consisting of cations of: Sb, Al and W; C is at least one cation selected from the group consisting of cations of: Fe, Zn, Al, Sb, Bi, W, Li, Ba, Nb and Sn; D is at least one cation selected from the group consisting of cations of: Ba, Mn, Al, Sb, Sn, and W; E is at least one cation selected from the group consisting of cations of: Fe, Ca, Mn, Sr, Eu, La, Zr, Ga, Sn and Pb; q, r, w, x and y are each independently a number from 0. 1 to 10 and y′ is a number from 0 to 10, z, z′, z″, z′″, and z″″ are determined using the amounts and oxidation states of all cations present in each formula. These catalysts can be used in C oxidation processes, especially butane oxidation processes.

An improved process for calcination and activation of a catalyst containing mixed oxides of vanadium and phosphorus (V/P/O) involving the addition of spray dried catalyst precursor to a fluidizing oxygen containing gas at a controlled rate such that the temperature is maintained at a range of 370 to 410. degree. C. (preferably 390. +-. 5. degree. C. ). The catalyst precursor experiences, in addition to rapid temperature rise, dehydration/calcination at this elevated temperature in the fluidized state for an average range of residence time of less than about 4 hours at 3. 5 atm of air or above, and up to 20 hours at 1 atm of air while simultaneously and continuously maintaining an average V. sub. ox of 4. 55 or less. Such a process is useful in preparing a V/P/O catalyst that exhibits enhanced activity for the oxidation of n-butane to maleic anhydride.
