Patent ID: 8846996

Claim:
A process for the preparation of an oxidative dehydrogenation catalyst of ethane to ethylene comprising co-comminuting: a) from 10 to 99 weight % of a mixed oxide catalyst of the formula V x Mo y Nb z Te m Me n O p , wherein Me is a metal selected from the group consisting of Ti, W, Hf, Zr and mixtures thereof; and x is from 0.1 to 3; y is from 0.5 to 1.5; z is from 0.001 to 3; m is from 0.001 to 5; n is from 0.001 to 2 and p is a number to satisfy the valence state of the mixed oxide catalyst; with: b) 90 to 1 weight % of an inert matrix selected from oxides of titanium, zirconium, aluminum, magnesium, yttrium, lanthanum, silicon and their mixed compositions or a carbon matrix, to produce particles having a size from 1 to 100 microns and forming the resulting particles into pellets having a size form 0.1 to 2 mm.
