Title: MOLYBDENUM BASED OXIDATION CATALYSTS
Abstract:
This invention concerns catalysts comprising a molybdenum compound of formula (I): VqMoAyOz, (II): NiMoxByOz', (III): VNiwMoxCy'Oz'', (IV): CoNiwMoxDyOz''', or (V): VNiwCorMoxEyOz'''' 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 C4 oxidation processes, especially butane oxidation processes.
