Abstract
A process for forming a catalyst useful for the production of an olefin from a hydrocarbon is disclosed. The process may include: admixing at least one of elemental metals and compounds to form a multi-metal composition comprising Mo, V, Nb, Te and at least one of Ni and Sb; adjusting the pH of the multi-metal composition by adding nitric acid; drying the acidified multi-metal composition; calcining the dried multi-metal composition; and grinding the calcined multi-metal composition. The ground multi-metal composition may then be sized or shaped to form a mixed metal oxide catalyst. Alternatively, the ground multi-metal composition may be treated with an acid, optionally annealed, and sized or shaped to form a mixed metal oxide catalyst.
