A new family of crystalline metal oxide compositions have been synthesized. These compositions are described by the empirical formula:where A is an alkali metal cation, ammonium ion and mixtures thereof, M is tungsten, molybdenum, or mixtures thereof. M' is vanadium, antimony, tellurium, niobium and mixtures thereof, and M'' is titanium, tin, indium and gallium, aluminum, bismuth and mixtures thereof. M' and M'' are optional metals. These compositions are characterized by having an x-ray diffraction pattern having at least one peak at a d spacing of about 3.9 Å. These materials can be used in various hydrocarbon conversion processes such as dehydrogenation. |
