Claim Text:
1. Mixed oxides comprising formula (I): possibly formed without a binder, wherein Y is a mixture of Mo and W in a molar ratio Mo/W greater than 0.1 and less than 10, Z is selected from Si, Al and mixtures thereof, O is oxygen, C is an organic component selected from a nitrogenated compound N, an organic residue R containing carbon and nitrogen, and a mixture of the residue R and nitrogenated compound N, said nitrogenated compound N being an amine having formula (A) wherein R R a, c and d are the number of moles of Ni, Z, and O, respectively, b is the sum of the moles of W and Mo p is the weight percentage of C with respect to the total weight of the compound having formula (I), a, b, c, and d are greater than 0 a/b is greater than or equal to 0.6 and lower than or equal to 1.5, (a+b)/c is greater than or equal to 0.3 and lower than or equal to 10, d=(2a+6b+Hc)/2 wherein and p is greater than or equal to 0 and lower than or equal to 40%, wherein said mixed oxides of formula (I) are characterized in that their diffraction patterns show the presence of an amorphous phase and a wolframite isostructural monoclinic crystalline phase, whose XRD pattern comprises the reflections indicated in the following table: the crystallinity degree of said mixed oxides being greater than 0 and lower than 100%.
