    Abstract: A catalyst useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) is disclosed. In accordance with a preferred embodiment of the present invention, a catalyst for use in ODH processes includes a MCrAlY support. M is preferably a base metal, or combination of base metals. A base metal is herein defined as a non-Group VIII metal, with the exception of iron, cobalt and nickel. Suitable base metals include Group IB-VIIB metals, Group IIIA-VA metals, Lanthanide metals, iron, cobalt and nickel. In a preferred embodiment, M is iron. Additionally, the catalyst may optionally include a Group VIII promoter. Suitable Group VIII promoters include Ru, Rh, Pd, Os, Ir, and Pt. In another preferred embodiment, M is a combination of a Lanthanide metal and iron with a front-loaded Group VIII promoter.

    Abstract: Catalysts and methods useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) are disclosed. The ODH catalysts are comprised of a Group VIII promoter metal present at trace levels. The Group VIII promoter metal is preferably platinum, palladium or a combination thereof and is preferably present at a promoter metal loading of between about 0.005 and about 0.1 weight percent. Optionally, the ODH catalysts include a base metal, metal oxide, or combination thereof. The optional base metal is selected from the group consisting of Group IB-IIB metals, Group IVB-VIIB metals, Group IIA-VA metals, scandium, yttrium, actinium, iron, cobalt, nickel, their oxides, and combinations thereof. The base metal is more preferably selected from the group consisting copper, tin, chromium, gold, manganese and their respective oxides and any combinations thereof. The base metal loading is preferably between about 0.5 and about 10 weight percent. Optionally, the promoter metal can be supported on a refractory material. The refractory support is preferably comprised of a material selected from group consisting of zirconia, stabilized zirconias, alumina, stabilized aluminas, and combinations thereof.

    Abstract: The present invention relates to a process for the preparation of synthesis gas (i.e., a mixture of carbon monoxide and hydrogen), typically labeled syngas. More particularly, the present invention relates to a regeneration method for a syngas catalyst. Still more particularly, the present invention relates to the regeneration of syngas catalysts using a re-dispersion technique. The re-dispersion technique involves the formation and removal of carbonyls with the active metals. The carbonyl formation and removal effectively re-disperses the catalyst metal.

    Abstract: The present invention includes an integrated process for the production of carbon filaments, comprising converting a portion of hydrocarbons to alkenes via oxidative dehydrogenation and further converting a portion of the alkenes to carbon filaments via contact with a metal catalyst. A portion of unconverted hydrocarbons remaining after oxidative dehydrogenation may also be further converted to carbon filaments via contact with the metal catalyst. The conversion of hydrocarbons to alkenes via oxidative dehydrogenation and further conversion of the alkenes and unconverted hydrocarbons to carbon filaments via contact with a metal catalyst may be carried out in the same or separate reactor vessels. A plurality of reactor vessels arranged in parallel may be used for the conversion of the alkenes and unconverted hydrocarbons to carbon filaments.
