    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.

    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： A method for generating syngas having a H2:CO ratio of less than 2:1 including selecting a predetermined desired syngas H2:CO molar ratio, selecting a hydrocarbon with a natural H2:CO molar ratio less than the desired ratio, selecting a hydrocarbon with a natural H2:CO molar ratio greater than the desired ratio, mixing the two hydrocarbons such that the natural H2:CO molar ratio of the mixture is the desired ratio, and catalytically partially oxidizing the mixture to produce syngas with the desired ratio.
