    摘要： 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.

    摘要： The present invention includes a process for producing carbon filaments and synthesis gas from a mixture of alkanes, preferably natural gas, comprising converting a first portion of the alkanes, preferably C2+ hydrocarbons, directly to carbon filaments and converting a second portion of the alkanes, preferably methane, to syngas. The natural gas may be separated into a first feed stream comprising ethane, propane, and butane and a second feed stream comprising methane. The first feed stream is fed to a carbon filament CF reactor to produce carbon filaments and hydrogen. The second feed stream is fed to a syngas production reactor to produce syngas. Alternatively, the natural gas is fed to at least one carbon filament reactor that is maintained at an effective temperature to convert C2+ hydrocarbons in the natural gas to carbon filaments and hydrogen, thereby filtering methane from the natural gas.

    摘要： The present invention provides a process for natural gas in the form, e.g., of stranded gas or associated gas to transportable liquids. More particularly, the present invention provides a process in which the gas is non-oxidatively converted to aromatic liquid, preferably in proximity to the welihead, which may be onshore or offshore. In one aspect, the present invention provides integration of separation of wellhead fluids into associated gas and crude with blending of the aromatic liquid derived from the gas with the crude. Alternatively, or in combination, in another aspect, the present invention provides integration of conversion of byproduct hydrogen to power with non-oxidative conversion of gas to aromatic liquid.

    摘要： 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.

    摘要： A method for the recovery of rhodium from spent supported catalysts. In one embodiment, a method for recovering rhodium from a host material includes roasting the host material in air at a temperature sufficient to convert at least a portion of rhodium to Rh2O3, leaching the host material in a solution with a leaching constituent which is reactive with Rh2O3 to form a first intermediate species, reacting the first intermediate species in a solution with an acidifying constituent or complexing agent to form a second intermediate species, and purifying the second intermediate species. Preferably, the roasting temperature is approximately from 600° C. to 800° C. for 0.5 to 10 hours. In some embodiments, the host material is ground to particles in the range of 0.1 to 10 mm.
