Abstract: A catalyst useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) is disclosed. The catalyst includes a base metal, metal oxide, or combination thereof and a refractory support. The base metal is selected from the group containing Group IB-VIIB metals, Group IIIA-VA metals, Lanthanide metals, iron, cobalt, and nickel. The metal oxide is selected from the group containing alumina, stabilized aluminas, zirconia, stabilized zirconias, titania, ytteria, silica, niobia, and vanadia. The catalyst does not contain any precious metals; it is activated by higher preheat temperatures. As a result, similar conversions are achieved at a considerably lower catalyst cost.

The catalysts comprise a mixture of metal oxides having as an important component nickel oxide (NiO), which give high conversion and selectivity in the process. For example, the catalyst can be used to make ethylene by contacting it with a gas mixture containing ethane and oxygen. The gas mixture may optionally contain ethylene, an inert diluent such as nitrogen, or both ethylene and an inert diluent.

Abstract: A solid acid-base catalyst contains vanadium pentoxide hydrate. Moreover, it is preferable that the vanadium pentoxide hydrate in the solid acid-base catalyst has a composition which is represented by the following general equation (1):V2O5.nH2Onullnull(1)(n: 0.1-3). Creation of the vanadium pentoxide hydrate was confirmed by measuring X-ray diffraction spectrum shown in FIG. 1. In accordance with the above arrangement, the solid acid-base catalyst can sufficiently display catalytic activity under mild conditions, and it can be suitably applied to various reactions, such as the syntheses of olefins or ethers through dehydration reactions of alcohols, the syntheses of aldehydes or ketones through dehydrogenation reactions of alcohols, hydrations and isomerization reactions of olefins, alkylations, esterifications, amidations, acetalizations, aminations, hydrogen shift reactions, aldol condensation reactions and polymerization reactions.
