<p>C-20-19-126 of THE DISCLOSURE An ammixidation catalyst is disclosed which has the empirical formula XaYbZcTedMo10x, from 0.5 to 30, b is from 1 to 80, c is from 0 to 50, d is from 1.5 to 25 and x is a number taken to satisfy the valence requirements of the metals present in the catalyst. In the empirical formula, X is one or more of Ce, La, a rare earth, Th, and Zr, Y is one or more of Nb, La, a rare earth, Th, Zr, Ta, and Ti, and Z is selected from Cr, Ga, Fe, P, W, Sn, and Bi, provided that at least one of Ce and Nb must be present. In other words, if X is not Ce then Y must be Nb, and if Y is not Nb then X must be Ce.</p> |
