A process and catalyst for the production of ethylene and/or acetic acid by oxidation of ethane and/or ethylene with a molecular oxygen-containing gas in the presence of a catalyst composition comprising the elements A, X and Y in combination with oxygen, the gram-atom ratios of the elements A:X:Y being a:b:c, wherein A = ModReeWf; X = Cr, Mn, Nb, Ta, Ti, V and/or W; Y = Bi, Ce, Co, Cu, Fe, K, Mg, Ni, P, Pb, Sb, Si, Sn, Tl and/or U; a = 1; b = 0 to 2; c = 0 to 2; d + e + f = a; d is either zero or greater than zero; e is greater than zero; and f is either zero or greater than zero. |
