Abstract: Methods for producing clean liquid/wax products from a slurry used in a Fischer-Tropsch reactor are disclosed. In general, one embodiment of the present invention comprises a solid/liquid filtration system having a filter medium comprising a substrate and a filter cake deposited on the substrate, wherein the filter cake is generated by deposition of solids from the slurry. The thickness of the filter cake can be maintained within a desired range by controlling the slurry velocity and/or the pressure differential across the filter medium. This invention relates to a method of operation of such filtration system which increases filtration cycle time and improved filtrate quality resulting in very low solid content in filtrate.

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: The invention relates to methods and apparatus for mixing a plurality of gases. The preferred embodiments of the invention comprise forming bubbles of at least two gases injected separately into a liquid, and passing said bubbles through a gas-induced turbulent liquid region to enhance gas transfer between bubbles and to thereby mix the at least two gases. Creating the gas-induced turbulent liquid region preferably includes using a high gas superficial velocity, and may further include using powered mechanical devices, static internal structures, fluid recirculation, or combinations thereof. The gas mixture is preferably supplied to a reaction zone. In one embodiment a bubble tank mixer supplies a gas mixture comprising oxygen and a hydrocarbon gas to an oxidation reaction zone disposed above said mixer. In alternative embodiments the reaction zone and mixer may be integrated into the same vessel.
