Abstract: Catalysts and methods useful for the production of olefins from alkanes via oxidative dehydrogenation (ODH) comprise at least one base metal and copper with an optional promoter. The catalyst preferably comprises a base metal and a copper-modified Groups 8, 9, or 10 metal on a support comprising alumina, zirconia, or mixtures thereof. Copper is preferably present in an amount of from about 0.1 to about 1.0 percent by weight of the total catalyst weight. The base metal preferably comprises manganese, chromium, gold, their corresponding oxides, or combinations thereof. The optional promoter preferably comprises platinum, palladium, iridium, rhodium, ruthenium, or any combinations thereof.

Abstract: The invention relates to a reactor comprising two reaction zones and processes for the production of alkenes from alkanes. A first reaction zone includes a combustion catalyst, and a second reaction zone comprises a heating zone in thermal contact with the first reaction zone. One process comprises generating heat and an effluent by the combustion of a fuel with oxygen in the first reaction zone; passing an alkane feed through the heating zone of the second reaction zone such that the alkane feed absorbs a sufficient amount of the heat generated in the first reaction zone to initiate the conversion of alkanes to alkenes in the second reaction zone. In other embodiments, the effluent comprises oxygen, and the second reaction zone excludes a catalyst; alternatively, the effluent is substantially free of oxygen, and the second reaction zone comprises a supplemental oxygen feed and may or may not include a catalyst.

Abstract: The invention relates to methods for improving the octane number of a synthetic naphtha stream and optionally for producing olefins and/or solvents. In one embodiment, the method comprises aromatizing at least a portion of a synthetic naphtha stream to produce an aromatized hydrocarbon stream; and isomerizing at least a portion of the aromatized hydrocarbon stream to produce an isomerized aromatized hydrocarbon stream having a higher octane rating than the synthetic naphtha stream. Alternatively, the method comprises providing at least three synthetic naphtha cuts comprising a C4-C5 stream; a C6-C8 stream and a C9-C11 stream; aromatizing some of the C6-C8 stream to form an aromatized hydrocarbon stream with a higher octane number; steam cracking some of the C6-C8 stream and optionally the C9-C11 stream to form olefins; and selling some portions of C9-C11 stream as solvents. In preferred embodiments, the synthetic naphtha is derived from Fischer-Tropsch synthesis.

Abstract: Methods are disclosed for converting propane and higher alkanes to their corresponding alcohols through a multi-step process with olefin as an intermediate. Methods are also disclosed for facilitating the transportation, purification or other treatment of propylene and higher olefins using a chemical conversion to the corresponding alcohol and reconversion to olefin. Methods are also disclosed for converting propane and higher alkanes to olefins using the corresponding alcohol as a temporary intermediate to minimize purification, transportation and/or other treatment costs.
